Question

A stone is thrown vertically upwards with an initial velocity, Ums-¹. It reaches a maximum height and returns to the ground. Find an equation for
I) the maximum height
ii) the velocity on hitting the ground

Answer 1

1) Maximum height = u^2/2g

2) velocity on hitting the ground = u

Answer 2

Answer:

1)Maximum height S=u2/2a.

2)Velocity on hitting the ground V=Initial velocity imparted to the stone U m/s.
