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 76.4 kg, but she is unsure of the mass of a large gas 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 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s. what is the mass of the canister?

90.3 kg

Explanation:

Given

Mass of astronaut

Initial velocity of canister

Final velocity of canister

Final speed of Astronaut

let M be the mass of canister

As there is no external force therefore we can conserve momentum

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

fossil fuels burn

cities become more industrialized
