Question

A force acts for 0.1 s on a body of mass 2.0 kg
initially at rest. The force is then withdrawn and
the body moves with a velocity of 2 ms. Find the
magnitude of force.
Ans, 40 N​

Answer 1

Answer:

T=. 1s

M=2kg

V=2m/s

U=0

Explanation:

V=u+at

2m/s=o+a×0.1s

a=20m/s^2

F=ma

F=2kg×20m/s^2

F=40n
