Block 1, of mass m1 = 1.70kg , moves along a frictionless air track with speed v1 = 25.0m/s. It collides with block 2, of mass m2 = 51.0kg , which was initially at rest. The blocks stick together after the collision.
Part A: Find the magnitude pi of the total initial momentum of the two-block system.
Part B: Find vf, the magnitude of the final velocity of the two-block system.
Part C: What is the change?K=Kfinal?Kinitial in the two-block system's kinetic energy due to the collision?
