Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.

Two blocks are connected by a massless string over a pulley, as shown at right. Block A has a mass of 20 kg, and Block B has mass m. The coefficient of static friction between Block A and the horizontal surface is μs = 0.30 and the coefficient of kinetic friction between Block A and the surface is μk = 0.20. The mass m of block B can be selected to be any value between 0 kg and 40 kg. The value of m is chosen, and the system is released from rest. This is repeated for many different values of m. 6) On the axes provided, graph the friction force Ff acting on block A vs. the mass m of block B. Note the value of important points on the graph such as discontinuities, maxima, and minima. Show your work.
