A ball is dropped from a height of 16 m on a horizontal floor. If it rebounds to a height of 9 m after striking the floor, the coefficient of restitution between ball and floor is
The magnitude of the kinetic friction bears a constant ratio to the normal reaction between two surfaces. The ratio being slightly less than that in the case of limiting friction
The force of friction always acts in a direction opposite to that in which a body is moving
For moderate speeds the force of friction remains constant but decreases slightly with the increase of speed
