Question

A small cube of mass m1= 1.0 kg slides down a circular and frictionless track of radius R= 0.5 m cut into a large block of mass m2= 4.0 kg. The large block rests on a horizontal and frictionless table. The cube and the block are initially at rest, and the cube m1 starts from the top of the path. Find the speed of the cube v1 as it leaves the block. Take g= 10.0 m/s2. Give your answer in m/s.

Answer 1

I just figured it out :)
