Question

Your brother's mass is 35.6 kg and he has a 1.3-kg skateboard. What is the combined momentum of your brother and his skateboard if they are moving at 9.50 m/s?
bobpursley
Momentum= combined mass * velocity.
Add the two masses (35.6 + 1.3) then multiply it by the velocity 9.5

So,
It's (36.9) 9.5
Answer: 350.55kg•m/s
