Question

ball is thrown vertically upwards with velocity 'u'. Calculate the velocity with which it falls to the earth again​

Answer 1

Answer:

When one throws a ball upwards with velocity 'u' its velocity decreases due to downward gravitational pull. It will reach a point where its velocity becomes zero.

Let the time taken by the ball to fall down from a height be 't'.

Using,v=u+gt

v=0+(9.8)t

v=9.8tm/s^2
