If a particle is moving along a straight line and following is the graph showing acceleration varying with time then choose the correct statement (s) for interval t = 0 to t = 8 sec, At t = 0, x = 0 and `v_(0) = 7 m//s`

Options

A. Its displacement can never be zero
B. Its velocity can never be zero
C. Its displacement can become zero
D. Its velocity can become zero

Answer

A, D

Explanation

Area under a-t graph gives us change in velocity. From this, it can be inferred that the velocity changes by more than 7 m/s, so it has to be zero once before the particle changes its direction of motion, also displacement of the body cannot never be zero as the particle continues to move further.
