Question
A player throws a ball upwards with an initial speed of $29.4 \mathrm{~m} \mathrm{~s}^{-1}$. What are the velocity and acceleration of the ball at the highest point of its motion?
✓
Answer
At maximum height, velocity of the ball becomes zero. Acceleration due to gravity at a given place is constant and acts on the ball at all points (including the highest point) with a constant value i.e., $9.8 \mathrm{~m} / \mathrm{s}^2$.
