3. You are standing in a moving bus, facing forward, when you suddenly slide forward as the bus comes to an immediate stop. What force caused you to slide forward? a) the force due to friction between you and the floor of the bus b) gravity c) There is not a force causing you to slide forward - it is due to inertia. d) the normal force due to your contact with the floor of the bus 4. A block...

2. A 5 kg block sits at rest on an inclined ramp which makes an angle of 24 degrees with respect to the horizontal. It is noted that even if the angle 0 is increased the block still does not slip. The coefficient of static friction for the bottom surface of the block and the surface of the ramp is us= 0.56. The magnitude of the frictional force acting on the block must be O 1 O O A. 50...
