A particle moves along a straight line path. After some time it comes to rest. The motion is with constant acceleration whose direction with respect to the direction of velocity is :

A

positive throughout motion

B

negative throughout motion

C

first positive then negative

D

first negative then positive

Text Solution

Verified by Experts

The correct Answer is:
B
Here velocity is decreasing, so acceleration will be oppsite to the direction of motion and hence, it will be negative w.r.t the direction of velocity till it comes to rest.
