Question

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
​

Answer 1

Answer:

(a) positive throughout the motion

Answer 2

Answer:

As the acceleration is constant hence velocity can't be negative it will be positive therefore option a is the answer.For velocity to be negative,acceleration must decrease
