A 0.5 kg block slides down a frictionless semicircular track from a height, h, and collides with a second 1.5 kg block at the bottom. The two blocks stick together via some Velcro and slide up the other side of the track. What height do the two blocks reach?

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

The discovery of the electron as a subatomic particle was a result of
