Momentum = mass X velocityImpulse = Force X timeImpulse = change in momentumF=ma

1. What is the average momentum of a 50 kg runner who covers 400m in 50s?

2. A cement truck of mass 10,000 kg moving at 15 m/s slams into a cement wall and comes to a halt. What is the force of impact (momentum) on the truck?

3. How fast is a player moving if they have a momentum of 4000 kg m/s and a mass of 100kg?

4. Calculate the impulse of an egg that hits the ground with a force of 50N over a time frame of .1 seconds/

5. How fast is a .25 kg egg move if it hits the ground with a force of 50N and it takes .15 seconds for impact?

6. Calculate the change in momentum of an football player ( 100 kg) moving at an acceleration of 5 m/s/s, when he hits another player in 2 seconds.
