Physics

If an object of mass m1 = 0.55 kg is sliding withoutfriction in the +x-direction on a level surface at a speed ofv1 = 0.72 m/s and it collides with a stationary object ofmass m1 = 0.55 kg, determine the total initial and finalmomenta (before and after the collision) as well as the totalinitial and final Mechanical Energy (before and after thecollision) for;

1) a perfectly elastic collision, and

2) a perfectly inelastic collision

Energy losses during an energy transformation process can bequantified as the efficiency;

e=useful energy out total energy in x 100%

3) State what the useful energies in and out are and thencalculate the efficiency for the perfectly elastic and theefficiency for the perfectly inelastic collisions describedabove.
