Answer:
The displacement is 
The distance is 
Explanation:
From the question we are told that
The height from which the ball is dropped is 
The height attained at the first bounce is 
The height attained at the second bounce is 
The height attained at the third bounce is 
Note : When calculating displacement we consider the direction of motion
Generally given that upward is positive the total displacement of the ball is mathematically represented as
Here the 0 show that there was no bounce back to the point where Billy released the ball
=>
Generally the distance covered by the ball is mathematically represented as
The 2 shows that the ball traveled the height two times
=>
The quantity of matter in a body regardless of its volume or of any forces acting on it.
The If a car is going round a curve , there is an acceleration because the direction of the velocity changes.
<h3>What is the direction of the velocity?</h3>
Now we know that if you throw the ball upwards, the motion is in opposite direction to gravity thus the ball is experiencing deceleration and the speed decreases. The velocity decreases and the acceleration is negative.
If the ball is coming down, then the ball is accelerated thus it speeds up and the direction of the acceleration is positive.
If a car is going round a curve, the vehicle is accelerating because the direction of the velocity changes even if its amount remains constant.
When a board is moving down a hill at 2 ms-1, it is experiencing an acceleration because the motion is in the same direction as gravity.
If a car is coming to a stop at a point, it experiences a deceleration and not an acceleration since the change of velocity with time is negative as the car comes to rest.
