An astronaut is performing a space walk outside the International Space Station. The total mass of the astronaut with her space suit and all her gear is 101 kg. A small leak develops in her propulsion system and 6.03 g of gas are ejected each second into space with a speed of 757 m/s.
She notices the leak 5.93 s after it starts.
How much will the gas leak have caused her to move from her original location in space by that time?
In the path shown below, the locations of a car driving around a track are shown at EQUAL time intervals where ?t = 20 s. The car starts with speed 40 m/s at x0 and uniformly slows down to 20 m/s from x0 to x2. The car then travels at a constant spee..
