Momentum

Open Ended
Padding helmets and mouthguards can protect athletes. How does the equipment do this? When two objects collide, which quantities affect the outcome? Will a large elephant like an elephant, always cause more damage than a smaller one, like a pebble? Does speed or contact time play a role? As you think about these questions, list what you know about momentum.

Multiple Choice
A 2200 kg vehicle traveling at 26m/s can be stopped in 21s by gently applying the brakes. It can be stopped in 3.8s if the driver slams on the brakes, or in 0.22s if it hits a concrete wall. What is the initial momentum?
546 kg*m/s
46,200 kg*m/s
57,200 kg*m/s
