The heavyweight boxing champion of the world punches a sheet of paper in midair, bringing it from rest up to a speed of 26.5 m/s

enyata [817]

corrected question:The heavyweight boxing champion of the world punches a sheet of paper in midair, bringing it from rest up to a speed of 26.5 m/s in 0.044 s . The mass of the paper is 0.003 kg. Part A Find the force of the punch on the paper

Answer:

Force=1.8N

Explanation:

Newtons third law states that in every action there is equal and opposite reaction.

The force of the punch will be the force that moves the paper by a speed of 26.5m/s.

$F=ma$

$F=m\frac{v-u}{t}$

m=0.003kg , v=26.5m/s u=0(the paper is punched from rest) t=0.044s

$F=0.003*\frac{26.5-0.044}{0.044}$

F=1.8N

Explanation:

The problem here was not the error; it was the failure of NASA's systems engineering, and the checks and balances in our processes, to detect the error. That's why we lost the spacecraft.
