Question
A body is thrown vertically upward with a velocity of 20
m/s. What will be its velocity at the highest point?Solution
At the highest point, the velocity of the object becomes zero, as it stops momentarily before falling down. Then gravity pulls it back. This concept is essential in freefall and projectile motion. The time to reach the top can be found using v = u - gt.
