Question

A body is projected up with an initial velocity of u m/s. It goes up to a height, ‘h’ meters in seconds' time. Then it comes back at the point of projection.

Considering negligible air resistance, which of the following statement is true?

पर्याय

• the acceleration is zero

• the displacement is zero

• the average velocity is 2hit

• the final velocity is 2u when body reaches projection point

Answer 1

the displacement is zero
