In a two dimensional motion,instantaneous speed `v_(0)` is a positive constant.Then which of the following are necessarily true?

A

The average velocity is not zero at any time

B

Average acceleration must always vanish

C

displacements in equal time intervals are equal

D

Equal path lengths are traversed in equal intervals

Verified by Experts

The correct Answer is:

D

In two dimenssional motion, ifinstantaneous speed is a positive constant, then equal path length are travered in equal intervals of time
