Question

If a moving body comes to rest, then its acceleration is- (a) Positive (b) negative (c) Zero (d) All of these depending upon initial velocity.

Answer 1

(b)negative is the answer

Hope it helps...

Answer 2

Answer:

b) negative

Explanation:

when a body is coming to rest after having initial velocity, it means that the body's final velocity is < initial velocity.

going by the equation a=v-u/t , v< u

we get negative values of a.

Hence deceleration
