Question

A particle is moving on a straight line path with constant acceleration directed along the direction of instantaneous velocity. Which of the following statements about the motion of particle is true. 

(a) Particle may reverse the direction of motion. 

(b) distance covered = magnitude of displacement 

(c) average velocity is less than average speed 

(d) average velocity = instantaneous velocity.

Answer 1

Answer is (b) distance covered = magnitude of displacement

The Particle is moving on the straight line path and there can be no reversal in the direction of motion.

Here distance covered = magnitude of displacement
