Question

A body of mass 10kg is moving with a velocity 20metre per second . A force is applied on the body on 25 seconds and it attains a velocity of 40 metre per second what is the force applied

Answer 1

Answer:

8N

Explanation:

Here

m=10kg

u= 20m/s

t= 25s

v=40m/s

a = v-u/t

=40-20/25

=20/25m/s

Now f=ma

=10*20/25

=8N
