A5.4 kg object has a velocity of 5 m/s. it collides with a 1.7 kg object which is not moving before the collision. after the collision, the first object has a velocity of 2m/s.

a) what is the impulse for the first object?

b) what is the impulse for the second object?

c) what is the second objects velocity after the collision if it was not moving before the collision?

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 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 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.
