Statement I: If a sphere of mass m moving with speed u undergoes a perfectly elastic head-on collision with another sphere of heavier mass M at rest ( M gt m ), then direction of velocity of sphere of mass m is reversed due to collision (no external force acts on system of two spheres). Statement II: During a collision of spheres of unequal masses, the heavier mass exerts more force on the lighter mass in comparison to the force which lighter mass exerts on the heavier one,
