Answer :

(a) False

It is assumed that the particle’s motion is random. As a result, this equation cannot calculate the particle’s average velocity.

(b) True

This equation can be used to depict the particle’s arbitrary motion.

(c) False

The particle’s motion is completely random. The particle’s acceleration may also be non-uniform. As a result, this equation cannot reflect the particle’s velocity in space.

(d) False
The particle’s velocity is arbitrary, and its acceleration may also be non-uniform. As a result, this equation cannot represent a particle’s velocity through space.

(e) True

This equation can be used to depict the particle’s arbitrary motion.
