Question

1. a body up with velocity u the greatest hieght to which it will rise is? a)u/g b)u^2/2g c)u^/g d) u/2g

Answer 1

A body up with velocity is u/g

Answer 2

Answer:

u^2/2g

Explanation:

by using v^2 - u^2 = 2as

              v = 0

              a = -g and s = h

  Now,    0^2 - u^2 = - 2gh

               - u^2 = -2gh

                 u^2 = 2gh

                 h = u^2/ 2g
