Determine the mass of this canister

Reference no: EM13334950

An astronaut in space cannot use conventional means, such as a scale or balance to determine the mass of an object. But she does have devices to measure distances accurately. She knows her own mass is 78.4 kg, but she is unsure of the mass of a large canister in the airless rocket. When this canister is approaching her at 3.50 m/s, she pushes against it, which slows it down to 1.20 m/s (but does not reverse it) and gives her a speed of 2.40 m/s. What is the mass of this canister?
