Isaac Newton discovered the three laws of motion. Which example BEST illustrates Newton's third law of motion, which describes action and reaction forces?
A. a rocket takes off the ground
B. a book slides forward on a seat when the car stops
C. a heavier ball falls at the same speed as the lighter ball
D. a vehicle rounds a curve and changes its acceleration
Answer:
The answer is A
Explanation:
When a rockets thrusters push on the ground the ground pushes back on the rocket with equal force in the opposite direction. Hence the rocket takes off.
Newtons third law of motion states, for every action there is an equal and opposite reaction.

A freight train initially moving at +10m/s decelerates at a rate of -0.1m/s^2. How far does it move in 30 seconds?
Answer:
255 [m].
Explanation:
1) the formula is (d - requred distance, V₀ - initial velocity, t - elapsed time, a - deceleration):
[tex]d=V_0t+\frac{at^2}{2};[/tex]
2) according to the formula above the required distance is:
d=10*30-0.5*0.1*900=300-45=255 [m].
Apply second equation of kinematics
[tex]\\ \tt\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]
[tex]\\ \tt\longmapsto s=10(30)+\dfrac{1}{2}(-0.1)(30)^2[/tex]
[tex]\\ \tt\longmapsto s=300+(-0.1)(450)[/tex]

A bus travels a total of 350km in 150 minutes. What was its average speed in km/h?#
Answer:
140km/hr
Explanation:
This is a simple converstion.
We know that the bus travels 350km/150min.
We want to know the speed in km/h. All we need to know is that per 1 hr there are 60 min.
350km/150min * 60min/1hr (we want to make sure that the value we are trying to eliminate, in this case the minute, is on the opposing side.)
(350*60)/150 = 21,000km/150hr
let's simplify to only per 1 hr.
21000/150 = 140
150/150 = 1
Therefore, the speed of the bus is 140km/hr
A bus travels a total of 350 km in 150 minutes, so the average speed of the bus in km/hr will be 140 km/hr.
What are Average Speed and Average Velocity?The object's average speed is how far it travels overall in a predetermined amount of time. The scalar quantity represents the average speed. It has no direction; instead, magnitude is used to describe it.
Average Speed = [tex]Total \ Distance/Total\ time[/tex]
An indicator of a vector is average velocity. Average velocity is calculated by dividing the change in position or displacement by the intervals during which it occurs. The average velocity may be positive or negative depending on how the displacement is dispersed. The standard international unit of average velocity is meters per second (m/s).
Average Velocity = [tex]Total \ Displacement/Total \ Time[/tex]
According to the question, the given values are :
Distance, d = 350 km
Time, t = 150 minutes or
t = 2.5 hours.
Average Speed = 350/2.5
Average speed = 140 km/hr
Hence, the average speed of the bus will be 140 km/hr.

A child pulls a balloon for 12m with a force of 1.0N at an angle 60 degrees below horizontal.How much work does the child do on the balloon?
Answer:
Distance for which the balloon has been pulled by the child = 12 meter
Force applied by the child to pull the balloon = 1.0 Newton
The angle below horizontal = 60 degree
These information's are already given in the question. Based on the above information's the answer to the question can be easily determined.
We know that
Work done = Force * Distance * Cos(60)
= 1 * 12 * (1/2)
= 1 * 6
= 6 Joules
So the work done by the child is 6 joules. I hope the procedure is clear enough for you to understand. Based on the above mentioned procedure, you can always solve problems of similar kind without taking any outside help.

A ball is launched at 5.5 m/s at 76 degrees above the horizontal. It starts and lands at the same distance from the ground. What are the maximum height above its launch level and the flight time of the ball?
The maximum height of the ball if A ball is launched at 5.5 m/s at 76 degrees above the horizontal is 1.45 meters.
What is distance?Distance, regardless of the direction of the travel, is the entire path that an object in motion has taken. Since the direction of motion is ignored while measuring distance, it is referred to as a scalar quantity. There is only one possible value for the distance: positive.
Given:
A ball is launched at 5.5 m/s at 76 degrees above the horizontal, It starts and lands at the same distance from the ground,
Calculate the maximum height as shown below,
Maximum height = [tex]v^2sin^2a / 2g[/tex]
Maximum height = 5.5² × sin²76° / 2 × 9.8
Maximum height = 30.25 × 0.97² / 19.6
Maximum height = 30.25 × 0.9409 / 19.6
Maximum height = 28.46 / 19.6
Maximum height = 1.45 m
Thus, the maximum height is 1.45 meters.

A 2 kg ball is dropped from a height of 60 m. Find its speed just before it hits the ground. Assume no friction. Answer
Answer:
-34.3m/s
Explanation:
first lets find the time befor it hit the ground by using free fall equation and we know we use that in one condition which is a constant acceleration in this case its a gravitational acceleration which is -9.8
[tex]h = \frac{1}{2} g {t}^{2} [/tex]
[tex]t = \sqrt{ \frac{2 \times 60}{9.8 } } = 3.5s[/tex]
now we know that the initial velocity its zero :
so applu the another kinematic equation which is
[tex]v = u - gt[/tex]
v is final velocity and u is the initial velocity and its equal zero.
v = - 9.8 × 3.5 = - 34.3

The initial potential energy of the ball,
