The heavyweight boxing champion of the world punches a sheet of paper in midair, bringing it from rest up to a speed of 26.0 m/s in 0.046 s . The mass of the paper is 0.003 kg.

Find the force of the punch on the paper.

Express your answer to two significant figures and include the appropriate units

Explanation / Answer

Force = m*a

m = 0.003 kg

Now using the equation

v = u + a*t

a = (v - u)/t

a = (26 - 0)/0.046 = 565.22 m/sec^2

So,

F = 0.003*565.22

F = 1.695 N = 1.7 N
