Question

A body moves with 10m/s towards east and then return towards west with the same velocity in 5 sec then a of the body is


Zero

Non zero​

Answer 1

Answer:

zero

Explanation:

given:

initial velocity (u) = 10m/s

final velocity (v) = 10m/s

time (t) = 5 seconds

to find :

acceleration (a) = v-u/t

calculation :

a = 10m/s - 10m/s / 5s

a = 0m/s / 5s

a = 0m/s² (as change in velocity is zero)

acceleration = 0
