What would be the final velocity if a 600g Cart 1, initially traveling 5.70m/s collided with a 200g Cart 2?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

The movement of electrons between atoms is called an

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
