Question

A body of mass 'm' kg starts from rest and travels a distance of 's' m in 't' seconds.Find the force acting on it.

Answer 1

find acceleration using 2nd equation of motion
s=ut+1/2at2
a=2s/t2
F=ma
F=2ms/t2

Answer 2

Answer:

The Force acting will be force = 2ms/t^2.

Explanation:

We now know that force equals mass multiplied by acceleration. However, there is no acceleration. As a result, we can apply the second equation of motion s = ut + (1/2) × at^2

Because the body began at rest, its initial velocity is zero, or u = 0.

∴ s = (1/2) × at^2

So we now get a = 2s/t^2

We can calculate force now that we have acceleration as a and know mass as m.

Force = mass × acceleration

By substituting the values we get force f = 2ms/t^2

Thus, the force is the push or pull that causes the velocity of a mass object to change.
