a rocket is launched upward from the ground with the initial velocity of 35 m/s . The magnitude of its acceleration is 5.0 m/s² . suddenly the engine breaks down at height h = 20km from the ground . neglect air resistance . calculate the speed of the speed of tge rocket at height 20km

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

A1200 kg car traveling north at 10 m/s is rear-ended by a 2000 kg truck traveling at 30 m/s. what is the total momentum before and after the collision?

Which situation will produce the greatest change of momentum
