`Astronaut Lynette's lifeline to her spaceship comes loose and she finds herself stranded, "floating" 52 m from the mothership. She suddenly throws her 3 kg wrench at 15 m/s in a direction away from the ship. If she and her spacesuit have a combined mass of 131 kg, how long does it take her to coast back to her spaceship?

What is the period of a wave traveling 5 m/s if its wavelength is 20 m/s

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.

What is the momentum of a 3 kg bowling ball moving at 3 m/s? 1 kg • m/s 3 kg • m/s 6 kg • m/s 9 kg • m/s
