A particle is projected vertically upward with velocity `u` from a point `A`, when it returns to the point of projection .

A

Its average speed is `u//2`.

B

Its average velocity is zero.

C

Its displacement is zero.

D

Its average speed is `u`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
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 `(u+0)//2=u//2`. The same will be the average speed for the whole motion.
