What is the mass of this canister

Reference no: EM13332844

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. But she does have devices to measure distance and time accurately. She knows her own mass is 75.3kg , but she is unsure of the mass of a large gas canister in the airless rocket. When this canister is approaching her at 3.70m/s , she pushes against it, which slows it down to 1.30m/s(but does not reverse it) and gives her a speed of 2.50m/s .

Part A What is the mass of this canister?

Part B How much kinetic energy is "lost" in this collision?
