Cart 1 with mass 4.44 kg collides with a stationary cart (cart 2) of mass 2.81 kg. Before the collision cart 1 has a velocity of 4.94 m/s to the right. After the collision, cart 1 has a velocity 1.11 m/s to the right and cart 2 has a velocity 6.05 m/s to the right.
A) What is the total momentum of the two cart system before the collision?
B) What is the total kinetic energy of the two cart system before the collision?
C) What is the total momentum of the two cart system after the collision?
D) What is the total kinetic energy of the two cart system after the collision?
E) Is this collision elastic or inelastic? Be wary of round-off errors here.

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?
