Explanation:

Given that,

The statue of Liberty is at a height of 46 m.

Jean Grey needs to fly from  rest on the ground to the top of the Statue of Liberty (46 m) in 2.0  seconds.

We need to find her minimum average acceleration during her  ascent. Let it is t. Using the second equation of motion to find it.

[tex]h=ut+\dfrac{1}{2}at^2\\\\h=\dfrac{1}{2}at^2\\\\a=\dfrac{2h}{t^2}\\\\a=\dfrac{2\times 46}{(2)^2}\\\\a=23\ m/s^2[/tex]

So, the constant acceleration is [tex]23\ m/s^2[/tex] for the entire distance.

Explanation: no clue on how to do it but i just got that answer on my accelus✨

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. The direction of the boat is northward and its magnitude is 1.633 m/s².

An object is said to be accelerated if there is a change in its velocity. The rate of change of velocity with respect to time is known as the velocity. It is a vector quantity and it has both magnitude and direction. It is the first derivative of velocity with respect to time.

Fx = 2200 [N]

Fa = 1350 [N]

F = √(Fₓ)² + (Fₐ)²

F = √(2200)² + (1350)²

F = 2581.18 N

Now using Newton's second law.

F = m×a

a = F / m

a = 2581.18 / 1580

a = 1.633 m/s²

Thus acceleration is 1.633 m/s² and it is northward direction.

Explanation:

Workdone by the rope is expressed using the formula;

W = Fd sin(theta)

F is the tension in the rope = 180

d is the displacement = 300m

theta is the angle of inclination = 15°

Substitute the given parameters into the formula;

W = 180(300)sin15

W = 54000sin 15

W = 13,976.23

Hence the workdone by the rope is 13,976.23Joules

Answer:

the correct answer is ( head ) just took it

The body loses up to 40 percent of its body heat through the head area.

The heat transferred to the surrounding by the thermal conductive substance per unit time.

40 to 45 percent of human body heat is lost through the head and neck due to increased blood flow as compared to the rest of the body.

Along with the wrists and ankles, this can be 60 percent.

Thus, the body loses up to 40 percent of its body heat through the head area.

Answer:

The nuclear force

Explanation:

hope this helps

Answer:

F = 12000 N = 12 KN

Explanation:

First we need to find the acceleration of the bad boys by using second equation of motion:

s = Vi t + (1/2)at²

where,

s = distance covered = 5 m

Vi = Initial Velocity = 0 m/s

t = time taken = 0.5 s

a = acceleration = ?

Therefore,

5 m = (0 m/s)(0.5 s) + (1/2)a(0.5 s)²

a = 2(5 m)/(0.5 s)²

a = 40 m/s²

Now, we calculate the force applied by Newton's Second Law:

F = ma

where,

F = force = ?

m = mass of bad guys = 300 kg

Therefore,

F = (300 kg)(40 m/s²)

F = 12000 N = 12 KN

Answer:

The height in which the book is dropped from is 1.28 m.

Explanation:

Mass of the book, m = 1.5 kg

initial velocity of the book, u = 0

final velocity of the bok, v = 5 m/s

The height in which the book is dropped from is given by;

v² = u² + 2gh

v² = 0 + 2gh

v² = 2gh

h = v² / 2g

h = (5)² / (2 x 9.8)

h = 1.28 m

Therefore, the height in which the book is dropped from is 1.28 m.

Answer:

a.-7.5 m/s

b.18.75 m

Answer:

58.24 Km/h.

Explanation:

From the question given above, the following data were obtained:

Distance (d) = 495 Km

Time (t) = 8 h 30 mins

Speed (S) =?

Next, we shall express 8 hours 30 mins to hours.

We'll begin by convert 30 mins to hour.

60 mins = 1 h

Therefore,

30 mins = 30 mins × 1 h/ 60 mins

30 mins = 0.5 hour.

Thus,

8 h 30 min = 8 + 0.5 = 8.5 hours

Speed is define as the distance travelled per unit time. Mathematically, it is expressed as:

Speed = Distance /time

With the above formula, we can obtain the speed as shown below:

Distance (d) = 495 Km

Time (t) = 8.5 hour

Speed (S) =?

Speed = Distance /time

Speed = 495 Km / 8.5 hour

Speed = 58.24 Km/h

Thus, the speed is 58.24 Km/h.
