Question

If the velocity of a body changes from 12m/s to 22m/s in 5sec, its acceleration is ________.

a) 2m/s2

b) m/s2

c) 62m/s2

d) m/s2​

Answer 1

Answer:

Given that,

The velocity of body changes from 12m/s to 22m/s

The time at which velocity changes is 5seconds

We know that,

Acceleration = final velocity-intial velocity/T

a =v-u/T

a =22-12/5

a =10/5

a =2m/s

The acceleration of a body is 2m/s

The option a is the answer

Thank you

I hope it help you
