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 masses are connected by a string. Mass mA rests on a frictionless inclined plane, while mB is initially held at a height of h above the floor. (a) If mB is allowed to fall, what will be the resulting acceleration of the masses? (b) If the masses were initially at rest, use the kinematic equations to find their velocity just before mass b hits the floor, (c) Use conservation of energy to find the velocity of the masses just before mB hits the floor. You should get the same answer as in part (b). EXPRESS YOUR ANSWER IN TERMS OF h, θ, g, mA, and mB.

6.12 Two blocks, each having a mass of 100 kg and resting on a horizontal surface, are to be pushed apart using a 30∘ wedge, as shown. The coefficient of static friction for all contact surfaces is 0.25 . Calculate the vertical force P required to start the wedge and the blocks in motion. Problem 6.12
