1. what is the kinetic energy of a 65 kg rocket traveling at 109 m/s? ( j ) type answer as a whole number (no decimals). type the number only, not the units. use commas: for example, type 100,000, not 100000 2. what is the momentum of the rocket in the previous problem? ( kg · m/s) type answer as a whole number (no decimals, no commas). type the number only, not the units.

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.
