An atom of mass m1 = m moves in the positive x direction with speed v1 = v. It collides with and sticks to an atom of mass m2 = 4m moving in the positive y direction with speed v2 = 3v/5. Find the resultant speed and direction of motion of the combination. (Specify the magnitude of the resultant speed in terms of v.) Find the kinetic energy lost in this inelastic collision.
