Block 1, of mass m1 = 2.90 kg , moves along a frictionless air track with speed v1 = 17.0 m/s . It collides with block 2, of mass m2 = 51.0 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.Express your answer numerically.

b) Find vf, the magnitude of the final velocity of the two-block system.Express your answer numerically.

c) What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?
