First, an object 1 with mass m and an object 2 with mass 2 m are moving on a straight line at velocities v1i=1.00 m/s and v2i= -2.00 m/s. Two objects collided inelastically, and the velocities of object 1 and object 2 changed to v1f and vf2, respectively. The velocity is positive in the right direction, and no external force is acting on these two objects. Find v1f and vf2 for cases (1) and (2) below, respectively.

(1) When two objects have a completely inelastic collision.

(2) When two objects have a rebound coefficient e = 0.8.
