Question

A block of mass m1 = 1.95 kg and a block of mass m2 = 5.50 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of θ = 30.0° as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks. A wedge in the shape of a right trapezoid is shown. A block of mass m1 is on the top horizontal surface on the left side. It is connected to a string which goes over a pulley of mass M and radius R. The pulley is at the beginning of the sloping surface of the wedge. At the other end of the string, a block of mass m2 is connected to it. This block is on the sloping surface of the wedge. The sloping surface makes an angle θ with the horizontal. (a) Draw force diagrams of both blocks and of the pulley. This answer has not been graded yet. (b) Determine the acceleration of the two blocks. (Enter the magnitude of the acceleration.) (c) Determine the tensions in the string on both sides of the pulley. left of the pulley N right of the pulley
