It pounces back in exactly the opposite direction going at the same 3 x 10° m/s. a) What was the magnitude of the change in momentum of the molecule? b) What was the magnitude of the impulse applied to the molecule? c) If the molecule interacted with the wall for 1 us (10-6 s), what was the average force of the wall on the molecule?

A particle is moving at a speed of less than c/2. If the speed of the particle is doubled, what happens to its momentum?
An enemy spacecraft moves away from the Earth at a speed of v = 0.800c (Fig. P9.19). A galactic patrol spacecraft pursues at a speed of u = 0.900c relative to the Earth.
