Question

an object of mass 2 kg, its velocity changes from 10 m/s to 20 m/s in 1 then force acting on it is

Answer 1

Explanation:

Given M=2kg , u = 10m/s , v = 20m/s , t = 1sec F=?

We know that F = MA ... A is unknown so let's calculate it.

v = u+at

20=10+a

2 = a

So Force = M × A = 2kg × 2m/s² = 4N
