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.
[tex]F=ma[/tex]
[tex]F=m\frac{v-u}{t}[/tex]
m=0.003kg , v=26.5m/s u=0(the paper is punched from rest) t=0.044s
[tex]F=0.003*\frac{26.5-0.044}{0.044}[/tex]
F=1.8N
