on A ball of mass m hits a floor with a speed v making an angle of incidence 0 45 with the normal rivom to the floor If the coefficient of restitution is e 1 2 of reflection 0 45 V find the speed of the reflected ball and the angle AIPMT Mains 2005 Since the floor exerts a force on the ball along the normal during the collision so horizontal component of velocity remains same and only the vertical component changes
