Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.
