Answer:
Explanation:
TRUE....
velocity is decreasing,that means an opposite motion along with straight motion is taking place that's why the velocity is decreasing.
Now if motion is opposite then at some point of time velocity will be 0
& we know that
a=v-u/t
(Obj. Will come at rest means final velocity is 0)
=0-u/t=negative
Means (-) acceleration..
