A block of mass m1 = 2.50 kg and a block of mass m2 = 6.50 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. Us g = 9.8 m/s^2.
(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.
