Hello Could you please explain how to do this...Calculate the momentum of a 110kg football player running at 8m/s.Compare the player’s momentum with the momentum of a 0.410kg football thrown hard at a speed of 25.0m/s.

Respuesta :

Given data:

Mass of football player,

[tex]M=110\text{ kg}[/tex]

Velocity of football player,

[tex]V=8\text{ m/s}[/tex]

Mass of the football,

[tex]m=0.410\text{ kg}[/tex]

Velocity of football,

[tex]v=25\text{ m/s}[/tex]

The momentum of a moving object is given as the product of its mass and velocity. Therefore, the momentum of the football player is given as,

[tex]\begin{gathered} P=MV \\ =(110\text{ kg})\times(8\text{ m/s}) \\ =880\text{ kg}\cdot\text{ m/s} \end{gathered}[/tex]

Therefore, the momentum of the football 880 kg.m/s.

The momentum of the football is given as,

[tex]\begin{gathered} p=mv \\ =(0.410\text{ kg})\times(25.0\text{ m/s}) \\ =10.25\text{ kg}\cdot\text{m/s} \end{gathered}[/tex]

Therefore, the momentum of the football is 10.25 kg.m/s.

On comparing, the momentum of football player is very large to that of the momentum of the football.
