Acar with a mass of 2000 kg and a truck with a mass of 4000 kg are both moving at 20 m/s. which of these statements is correct? a. the car's momentum is smaller than the truck's momentum. b. the car's momentum is larger than the truck's momentum. c. the car and the truck have the same momentum.

Why is there friction between objects

What properties of a moving object are used in determining the object's energy of motion

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?
