Question

A force of 10 N acts on a body of mass 2 kg for 3 s, initially at rest. Calculate:
The velocity acquired by the body.

Answer 1

Time for which force is applied =3 s.
Mass of the body = 2 kg.
Initial speed of body = 0 ms^-1
Force applied = 10 N.
We know F X t = m (v - u)
10 X3 = 2 (v- 0)
v = 15 ms^-1.
