Aboxer punches a sheet of paper in midair and brings it from rest up to a speed of 30 m/s in 0.060 s .
if the mass of the paper is 0.003 kg, what force does the boxer exert on it? include units.

Force exerted, F = 1.5 N

Explanation:

It is given that, a boxer punches a sheet of paper in midair and brings it from rest up to a speed of 30 m/s in 0.060 s.

i.e. u = 0

v = 30 m/s

Time taken, t = 0.06 s

Mass of the paper, m = 0.003 kg

We need to find the force the boxer exert on it. The force can be calculated using second law of motion as :

F = 1.5 N

So, the force the boxer exert on the paper is 1.5 N. Hence, this is the required solution.
