Question

A player throws a ball vertically upwards.What is the direction of acceleration during upward motion? and what is the velocity at the highest point of motion?

Open in App

Solution

when the ball is going upward direction of acceleration,
direction of acceleration is in vertically downward direction
so it is taken as -g(acceleration due to gravity)
velocity at heighest point =0 ,As the ball is at rest at heighest point
