1. A mass m moves without friction on the inclined surface of a wedge of mass M.The wedge in turn slides without friction on a horizontal surface (ground). Thewedge is pushed (or pulled) by an external force F. (a) What is the force to keep Mfrom moving? (b) What is the force required to keep m stationary with respect to thewedge? (Hint: Ncos0 = mg. Why?) (c) What is the minimal force to make m falldown vertically as viewed from the ground? (Hint: N is zero. Why?)mF, pushF, pullMGround

A block of mass ?=353 gm=353 g is dragged with a string across a rough horizontal table. The string tension is ?=2.63 N,T=2.63 N, and it pulls upward at an angle of ?=44.0∘ϕ=44.0∘ with the horizontal. At one particular instant, the block is moving at a speed of ?=5.70 m/s.v=5.70 m/s. The coefficient of kinetic friction between the block and the table is ?k=0.699. What is the power ?TPT supplied to the block by the string tension? What is the power ?fPf supplied by the force of friction?
Connected objects with inclined plane problem. Consider the figure where you have two boxes connected by a string over a pulley. The smooth (frictionless) ramp is inclined to a an angle of 35° with the flat ground, and the box on the ramp has a mass of 6.40 kg. The mass of the 6.4 kg hanging box is m = 3.05 kg. You don't need to consider significant figures in your answer, but don't round excessively partway through your calculations. 35° Find (a) the direction and (b) the magnitude of the hanging box's acceleration.
