As shown, the incline has mass M and is fastened to the stationary horizontal tabletop. The block of mass m is placed near the bottom of the incline and is released with a quick push that sets it sliding upward. The block stops nearthe top of the incline as shown in the figure and then slides down again, always without friction. Find the force that the tabletop exerts on the incline throughout this motion in terms of m, M, g, and θ.
Two blocks are joined by an inextensible cable as shown. The mass of block A is 124.2 kg and the mass of block B is 274.6 kg. If
the system is released from rest, determine the acceleration (in m/s² ) of block B. Assume that the coefficient of friction
between block A and the plane is uk = 0.41 and that the pulley is weightless and frictionless.
Round off only on the final answer expressed in 3 decimal places. Use g = 9.81 m/s²

B
The three blocks with weights as shown in the figure are placed on a 20o incline so that they are in contact with each other and at rest. Determine which, if any, of the blocks will move and the friction force acting under each. Assume that under blocks A and C, the coefficients of friction are fs = 0.50 and fk = 0.40 while under B they are fs = 0.30 and fk = 0.20
