26. Two objects with masses m, = 10.0 kg and m2 = 20.0 kgare connected by a light string that passes over a frictionlesspulley with a mass of 5.00 kg and a radius of 2.00 m asm2shown in the figure. The object m, is held at rest on the floor,and m2 rests on a fixed frictionless incline of 0 = 40.0°. Theobjects are released from rest, and m, slides down theincline. Assume that the pulley can be modeled as a solidcylinder.т1Determine the angular acceleration of the pulley.40.0°
