One hazard of space travel is debris left by previous missions. There are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. Calculate the force exerted by a 0.130 mg chip of paint that strikes a space shuttle window at a relative speed of 4.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. Such a collision chipped the window of the ill-fated Challenger in June 1983, causing $50,000 of damage.
The Hulk (200 kg of pure angry muscle) collides head-on with a truck (2,500 kg). If the Hulk was running at 10.0 m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? (Hint: be careful about directions here, either the Hulk or the truck needs a negative initial velocity, I’ve left it up to you which one gets that negative initial velocity, but the final answer is just the speed, so if you wind up with a negative final velocity, drop the minus sign)

Timmy had stopped his cart with a of mass 500 kg just before a 30degree hill covered in ice. He was stuck from behind by a 1500 kg coach - of mass1500 kg – travelling at 20 m/s. The two vehicles stuck together and slid up the hill. How far up the slope did they go?
Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2u, while the second was traveling at speed u at an angle south of east (as indicated in the figure).

lease answer the following question(s): 1. Two manned satellites approach one another at a relative speed of 0.29 m/s, intending to dock. The first has a mass of 4.0x 10³ kg, and the second a mass of 7.5x10³ kg. If the two satellites collide elastically rather than dock, what is their final relative velocity?
