A ball is moving at 4.5 m/s and has a momentum of 75 kg. m/s. What is the ball's mass?

A 2.0-kg ball has a momentum of 25 kg.m/s. What is the ball's speed?

A 1.0-kg ball has a momentum of 12 kg.m/s. What is the ball's speed?

A ball is moving at 7.0 m/s and has a momentum of 100 kg.m/s. What is the ball's mass?

A constant force of 20 N acts on a 10.0 kg object for 5.0 s. What are the changes in the object's momentum and velocity?

Ow guy, at least show your work so you can be guided because we certainly can't do any of it for you. Nor is there a need to make every problem a separate thread.

Every one of these can be solved using the relationship: momentum = mass times velocity. Try it - post back with your answers and we'l check them for you.
