If a sphere of mass moving with speed undergoes a perfectly elastic head–on collision with another sphere of heavier mass at rest , then direction of velocity of sphere of mass is reserved due to collision (no external force acts on system of two spheres)

Statement2:

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

a)

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1

b)

Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
