A 5kg block sits on a wedge (1.5m high and 3m long at the bottom). Another block hangs vertically from a pulley as shown in the diagram. The coefficient of static friction between block m1 and surface of wedge is.4 while the coefficient of kinetic friction is .25. Assume that the pulley is massless and frictionless.

Draw a free body diagram for each block. Carefully label each force.

Calculate the magnitude of frictional force and find the mass of block 2 if the system shown is in equilibrium. Show all your work.

What do you think will happen to the same system if you double the mass of block 2? Carefully justify your answer

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...
