6 Two Blocks on an Incline with a Pulley

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. 00:00 - Read the Question 00:44 - Draw the Free Body Diagrams 02:32 - Sum of Forces on Block 2 05:18 - Sum of Forces on Block 1 06:40 - Sum of Torques on the Pulley 11:02 - Combine the Equations 16:12 - Find the two Tensions 19:24 - Recap
