Two blocks of equal mass are sliding on an inclined plane, as shown in the image below. At t = 0 s, the blocks are moving towards each other with equal speeds. A short while later, the blocks collide elastically and bounce off of one another. Which graph correctly describes how the center of mass (C.O.M.) velocity of the two-block system changes over time? Assume both blocks remain on the ramp for the duration of the time shown on the graph. Neglect drag and friction. The positive direction is defined as up the incline, as shown on the image above. B. C. D.

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.

part 1 of 2 A block of mass 1 kg and one of mass 7 kg are connected by a massless string over a pulley that is in the shape of a disk having a radius of 0.39 m, and a mass of 9 kg. In addition, the blocks are allowed to move on a fixed block-wedge of angle 31∘, as shown. The coefficient of kinetic friction is 0.25 for both blocks. What is the acceleration of the two blocks? The acceleration of gravity is 9.8 m/s2. Assume the positive direction is to the right. Answer in units of m/s2. part 2 of 2 Find the tension in the horizontal part of the string. Answer in units of N.
