A space shuttle can carry 23 tons of cargo into space. If a shuttle is launched with 22 tons of cargo instead of 23, how does the shuttle's motion change?

A. The shuttle’s acceleration increases because it has less mass.
B. The shuttle’s acceleration decreases because it has less mass.
C. The shuttle has less force moving it because it has less mass.
D. The shuttle has more force moving it because it has less mass.

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 77.4 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?

Ahockey player of mass 82 kg is traveling north with a velocity of 4.1 meters per second he collides with the 76 kg player traveling east at 3.4 meters per second if the two players locked together momentarily in what direction will they be going immediately after the collision how fast will they be moving
