Question

a body is projected vertically up with 'u'. its velocity at half its maximum height is?

step wise plzz

Answer 1

Hey!

______________

Initial velocity = u

We know,

v^2 - u^2 = 2gh

Height = h/2

Putting values in equation -

v^2 - u^2 = 2gh/2
v^2 = u^2 - 2gh/2
v^2 = u^2 - gh

v= √u^2 - gh
