A runner completes two laps around a 400-m track. She runs the first lap in 1 min 32 s, and the second lap in 1 min 49 s. What is her average speed?

Answers

Answer:

The average speed is 3.98 [tex]\frac{m}{s}[/tex]

Explanation:

Speed ​​is a scalar quantity that shows the relationship between the distance traveled and the time taken.

In other words, speed is a scalar quantity that determines the ratio of the distance traveled by a body or object and the time it takes to cover that distance. Speed ​​does not take direction into account.

Average speed refers to the total distance traveled during a given time, which is equivalent to saying that it is the ratio of distance and time.

[tex]average speed=\frac{total distance}{totaltime}[/tex]

In this case you know that a runner completes two laps around a 400 m track, so the total distance traveled is 800 m.

On the other hand, you know that the runner completes the first lap in 1 min 32 s, and the second lap in 1 min 49 s. Being 1 min equivalent to 60 s, the first round is completed in 92 s and the second round in 109 s. So the total time to complete the two laps around the track is 92 s + 109 s = 201 s.

That is, being:

total distance=800 mtotal time= 201 s

and replacing in the definition of average speed:

[tex]average speed=\frac{800 m}{201 s}[/tex]

you get:

average speed= 3.98 [tex]\frac{m}{s}[/tex]

The average speed is 3.98 [tex]\frac{m}{s}[/tex]

Answer:

3.98 m/s

Explanation:

To find speed, use the formula:

Speed = Distance / time

The Distance is 400 + 400 = 800 m

The time in seconds is (60 + 32) + (60 + 49) = 201 sec

Now use the formula

Speed = 800 m / 201 s = 3.98 m/s

An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark. What was the total distance the ant traveled?

Answers

Given :

An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west.

It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark.

To Find :

The total distance the ant traveled.

Solution :

Total distance travelled by ant = (distance between 14 and 20 inch mark) +

                                                      (distance between 20 and 16 inch mark)

Total distance = (20-14 ) + ( 20-16) = 6 + 4 = 10 inch.

Therefore, total distance the ant traveled is 10 inch.

Hence, this is the required solution.

A train rolls at a constant speed of 10 m/s across a horizontal track. A child standing on the flatbed of the train throws a ball so that it appears to move straight up to an observer standing next to the track. a. What is the horizontal speed of the ball relative to the observer?

Answers

Answer:

The answer is 10m/s

Explanation:

Given that the child is in the train, and that the train is moving at a speed of 10m/s, and also the child is standing on the flatbed, hence the child is not moving, therefore the velocity of the child is 10m/s relative to the observer

Also, when the child throws the ball horizontally relative to the observer the horizontal speed is also 10m/s.

therefore the speed of the ball is also 10m/s to the observer

Answers

Answer:

a

 [tex]a = 21.7 \ m/s^2[/tex]

b

[tex]F = 108.5 \ N[/tex]  

Explanation:

From the question we told that

   The mass is  m  =  5 kg

    The initial speed [tex]u = 5 m/s[/tex]

    The time taken to attain [tex]v = 70 \ m/s[/tex] is  t =  3 s

   

Generally from kinematic equation we have that

     [tex]v = u + at[/tex]

=> [tex]70 = 5 + a * 3[/tex]

=>  [tex]a = 21.7 \ m/s^2[/tex]

Generally  the force acting is mathematically represented

        [tex]F = m * a[/tex]

=>      [tex]F = 5 * 21.7[/tex]  

=>      [tex]F = 108.5 \ N[/tex]

If an astronaut weighs 750 N on the ground, what will he weigh in earth orbit 400 km above the earth’s surface?
R_earth = 6.38 × 10^6 m,
m_earth=5.97×10^24 kg
G=6.674×10^−11 Nm^2/kg^2

Answers

Answer:

The weight of the astronaut in Earth's orbit 400 km above the Earth's surface is 664.115 N

Explanation:

The given parameters are;

The weight of the astronaut on the ground = 750 N

The height of the orbit above the Earths surface = 400 km

The radius of the Earth = 6.38 × 10⁶ m

The mass of the Earth = 5.97 × 10²⁴ kg

The universal gravitational constant G = 6.674 × 10⁻¹¹ Nm²/kg²

From Newton's law of universal gravitation, we have;

[tex]Weight \ on \ ground \ of \ astronaut \ F_W =G\times \dfrac{M_{Earth} \times m_{astronouat}}{R_{Earth}^{2}} = 750 \ N[/tex]

[tex]F_W =6.674 \times 10^{-11}\times \dfrac{5.97 \times 10^{24}\times m_{astronouat}}{(6.38 \times 10^6)^{2}} = 750 \ N[/tex]

[tex]m_{astronaut}[/tex] = ((6.38 × 10⁶)² × 750)/((6.674 × 10⁻¹¹) × (5.97 × 10²⁴)) ≈ 76.62 kg

The mass of the astronaut ≈ 76.62 kg

For the weight of the astronaut  in Earth orbit 400 km (400 × 10³ m) above the Earth's surface, we have;

[tex]F_{W \ in \ orbit} =6.674 \times 10^{-11}\times \dfrac{5.97 \times 10^{24}\times 76.62}{(6.38 \times 10^6 + 400 \times 10^3)^{2} } = 664.115 \ N[/tex]

The weight of the astronaut in Earth's orbit 400 km above the Earth's surface = 664.115 N.

how does shape of object affect friction

Answers

Answer:

There are three types of friction.

1. Slanting friction

2. Sliding friction

3. Rolling friction

In the first two types of friction, the body of the object will come in contact with the irregularities on the surface more than in the case of rolling friction, thus a heavy box in square shape will have more friction than a heavy-duty vehicle.

This is also the reason why all vehicles are having wheels as they reduce friction and makes transportation easier and many people suggest to use a small log of wood to be placed on the bottom of a heavy box with flat bottom so it can moved easily due to reduction of friction

If the object is in Circle shape then you the friction a flat bottom then it will have increased friction

What is the magnitude of a rope that is being polled 300n to the left and 425n to the right

Answers

Answer:

FT = 125 [N], to the right

Explanation:

Both forces are characterized by being vectors, and these are applied in opposite directions so the difference between them will be the result of the sum of the forces.

FL = 300 [N]

FT = 425 [N]

FT = Total force

FT = 425 - 300 = 125 [N]

Since the magnitude of the force is positive, we conclude that the resultant of these forces is to the right.

Explanation:

hope it helps♡ ;)

An object is accelerating if there is a change in speed and there is a change in direction, therefore the correct answer is option A.

What is acceleration?

The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².

Even if the magnitude of the velocity not changing even the change in the direction would lead to acceleration,

uniform circular motion is one of the best examples where the speed is constant but the direction is changing continuously

Thus, An object is accelerating if there is a change in speed and there is a change in direction, therefore the correct answer is option A.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The gravitational constant, denoted by the capital letter G, is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
