Two particles of mass m₁= 1.5 kg and m₂= 3.5 kg undergo a one-dimensional head-on collision as shown in Figure P7.21. Their initial velocities along x are v_1i= 12 m/s and v_2i= -7.5 m/s. The two particles stick together after the collision (a completely inelastic collision).?

(a) Find the velocity after the collision.?

(b) How much kinetic energy is lost in the collision?
