Question

What force will change the velocity of an object of mass 2.5 kg from 5 metre per second to 10 metre per second in 5 second

Answer 1

Answer:

2.5 N

Explanation:

First find acceleration from

v=u+at

where

v=10m/s

u=5m/s

t=5s

acceleration will be= 1

Now apply the second law of Newton

F=ma

Force=2.5x1

Force= 2.5 N

Hope you understand

Answer 2

Answer:

2.5 N
