pi = m1vi1 + m2vi2 = (2.10)(29.0) + (57.0)(0)
Block 1 of mass m1 = 2.10 kg, moves along a frictionless air track with speed v1 = 29.0 m/s . It collides with block 2, of mass m2 = 57.0 kg, which was initially at rest. The blocks stick together after the collision.
A) Find the magnitude pi of the total initial momentum of the two-block system.
B) Find the magnitude of the final velocity of the two-block system.
