Momentum = mass X velocity
Impulse = Force X time
Impulse = change in momentum
F=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.
