Question

a constant force acting on a body of mass 4kg changes its velocity from 2m/s to 4m/s in 4s. what is the force?​

Answer 1

Answer:

2 Newton

Explanation:

from newton second law

F = ma

as we have the mass equals 4 kg

we need to get the acceleration which will be change in velocity over change in time

a = ∆V/∆t = (4-2)/4 = 0.5

so F = 4 * 0.5 = 2

Answer 2

Answer:2N
