Consider the system in the picture below: a cart of mass M with a static friction coefficient u is connected through a massless string to a hanging mass m. M is a capital letter, m is lower case. Write them as such, or vour equations will be confusing, M We want to find the maximum value of the hanging mass m such that the system is in equilibrium. 1. Free body diagram (FBD): Draw a FBD for each: the Cart and the hanging mass. Clearly show all the forces. 2. Clearly write the equilibrium equations for the cart in the horizontal and vertical direction. 3. Clearly write the equilibrium equation for the hanging mass. 4. Solve the system of the three equations above for the hanging mass m. Show your calculation to get credit. 5. What would happen if mass m exceeds this value? Explain.

A block of mass 7 kg is placed on top of a block of mass 10 kg, which in turn sits on a frictionless horizontal surface, as shown in the figure. A force F = 20 N is applied to the 10 kg block, and the 7 kg block is held in place by a string attached to the wall. There is static friction ( µs=0.1) between the blocks, which keeps the lower block from moving. a) Demonstrate the free body diagram and the motion equation of the system. b) Calculate the acceleration of the block 10 kg. c) Calculate the tension T.
