Inelastic Collision

Block 1, mass m1= 7.10 kg , moves along a frictionless air track with speed v1 = 11.0 m/s . It collides with block 2 of mass m2 = 59.0 kg , Which moves initially with speed 4.30 m/s , toward the first block , The block stick together after the collision .

a) Find the magnitude P1 of the total initial momentum of the two-block system .

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

c) What is the change delta K= K final – K initial in the system’s kinetic energy due to the collision ?
