(12.5 pts a) (2.5 pts) What is the maximum frictional force acting on the box when it is not moving? b) (2.5 pts)...
. (5 marks) A piano has a mass of 515 kg. If the coefficient of static friction between the piano and the wooden floor is u=0.238, how much force is required to start the piano rolling across the floor? (5 marks) A 8.25 kg box is being pushed on a horizontal rough surface with a force of 55.0N. The kinetic friction force on the box is 38.5 N. Calculate the magnitude of the box's accelera- tion.
16. A force of magnitude 25.0 N is applied to a box of mass m2 = 2.0 kg. The force is directed up a plane tilted at an angle of 60.0. The box is connected by a cord to another box of mass m1 = 2.5 kg. The floor and pulley are frictionless, the ramp has a coefficient of friction of μ,-0.15, and the masses of the pulley and cord are neglible. a. Draw the free-body diagrams for the two...

1. What force is necessary to pull a 20.0-kg wooden box at a constant speed over a wooden floor at a constant speed over a wooden floor by a rope that makes an angle of 30° above the horizontal? The coefficient of kinetic friction (wood on wood) is 0.30. 2. A 50-kg balikbayan box rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the box just begins to move when your force...
