Question

In an experiment, a small block slides down a track and hits a second identical block at the edge of a desk above the floor. The first block is moving horizontally when it hits the stationary block, and the two collide off-center. As a result, the two blocks hit the floor moving in different directions. The first block hits the floor a distance of at an angle of from the centerline (a line along the original trajectory of the first block), and the second block hits the floor a distance of at an angle of from the centerline. What was the speed of the first block when it hit the second block on the track?
