Question

A car is moving with the speed of 40 m per sec. After 5 sec it's speed changes and it became 60 m per sec. Find out acceleration

Answer 1

Answer:

let u=40 and v=60

a=v-u/t

a=60-40/5

=4

Answer 2

Answer:

4m/s square

Explanation:

initial velocity = 40m

final velocity = 60m

time = 5sec

acceleration =?

acceleration = v-u/t

= 60-40/5

= 20/5

= 4m/s square
