Applied Mechanics and Graphic Statics
A ball is dropped from a height of 2.25 m on a smooth floor and rises to a height of 1.00 m after the bounce. The coefficient of restitution between the ball and the floor is
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
All of these
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
