Question

The mass of a basketball is three times greater then the mass of a softball. Compare the momentum’s of a softball and a basketball if they both are moving at the same velocity.

Answer 1

Let m = the mass of the softball.
Then the mass of the basketball is 3m.

By definition, momentum = mass * velocity.
If both the softball and basketball move at the same velocity, v, then
Momentum of the softball = mv
Momentum of the basketball = 3mv

Answer: The momentum of the basketball is 3 times that of the softball.
