Find, the magnitude of the final velocity of the two-block, Ask an Expert

Academics

Block 1, of mass = 9.90 kg, moves along a frictionless air track with speed = 13.0 m/s. It collides with block 2, of mass = 27.0 kg, which was initially at rest. The blocks stick together after the collision.

Find the magnitude of the total initial momentum of the two-block system. (kg*m/s)

Find , the magnitude of the final velocity of the two-block system.
