Question

A ball is projected vertically upwards with an initial velocity ‘u goes to a maximum height ‘h’ before touching the ground. What is the value of ‘h’ ?

Answer 1

using formula  

v^2=u^2+2as

find the answer.

here, v=0, s=h, a=g.

.: u^2+2gh=0

.: u^2=-2gh

.: h=u^2/g.

using formula

12=u^2+2 as

find the answer

here, v=0, s=h, a=g.

u2-2gh

h-u^2/g
