object #1 slides along a surface (μk = 0.15) that makes a 20º angle with respect to the horizontal. Both objects are connected by a massless string that runs over a frictionless pulley (m = 10 kg, r = 0.25 m). Object #1 has a mass of 5 kg and object #2 has a mass of 20 kg. Apply Newton’s Second Law to each of the three objects to obtain a system of three equations and three unknows that can be solved to find the tensions and acceleration of this system. Then calculate the final speed of object #2 after dropping a distance of 2 m.
