Question

Speed of a body on reaching the point from where it was projected vertically upward with velocity u is

Answer 1

Answer:

A particle is projected vertically upward with velocity u from a point A, when it returns to the point of projection . Its average speed is u/2.

Explanation:

A::B::C

Solution :

For vertically projected body, if it returs to the starting point, deslpacement and average veerage velocity become zero. As acceleration is constant, average speed during upward or downward motion is

. The same will be the average speed for the whole motion.
