I think I chose the correct answer. In a closed system, two carts have a compressed spring between them. One of the carts has a total mass, including its contents, of 2.0 kg, and the other has total mass of 1.0 kg. Which cart experiences the momentum change of greater ...

A 10 kg cart was observed moving north with a speed of 15 m/s before it collided with an identical cart moving south at 10 m/s. The collision was observed to cause the carts to couple and move together as one. What is in kg m/s the combined momentum of both carts before the ...

Physics
A cart of mass m1 = 12 kg slides down a frictionless ramp and is made to collide with a second cart of mass m2 = 19 kg, which then heads into a vertical loop of radius 0.23 m. Determine the height h from which cart 1 would need to start to make sure that cart 2 completes the ...

last physics problem!
A ball of mass 522 g starts at rest and slides down a frictionless track, as shown below. It leaves the track horizontally, striking the ground a distance x = 0.93 m from the end of the track after falling a vertical distance h2 = 1.18 m from the end of the track. (a) At what ...
