Question

A table tennis ball with a mass of 0.003kg and soccer with a mass of 0.43 kg. are both set in motion at 16 m"s. Calculate and compare the momenta of both balls.

Answer 1

Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= ( kg-m/s ) I use the subscript "t" for tennis. Momentum of Soccer ball Ps= 0.43 x 13m/s = ( km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.

Answer 2

`\texttt{Ration of moment of soccer ball to table tennis ball}=(6.88)/(0.048)=143.33`

Step-by-step explanation:

Linear momentum is product of mass and velocity.

Mass of table tennis ball = 0.003 kg

Mass of table soccer ball = 0.43 kg

Velocity of both balls = 16 m/s

Momentum of tennis ball = 0.003 x 16 = 0.048 kgm/s

Momentum of soccer ball = 0.43 x 16 = 6.88 kgm/s

`\texttt{Ration of moment of soccer ball to table tennis ball}=(6.88)/(0.048)=143.33`
