Momentum and collisions problem: two 1 kg boxes collide on a frictionless surface, with one moving at 5 m/s and the other stationary. After collision, they stick together.
Diagram showing a physics problem about momentum and collisions, illustrating two 1 kg boxes before and after a collision on a frictionless surface. The first box moves at 5 m/s, the second is stationary. After the collision, the boxes stick together and move as one.
