A Mass M1 Is Connected by a Light String That

Question 44

Multiple Choice

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless incline as shown in the figure.There is no slippage between the string and the pulley.The pulley has a radius of 30.0 cm and a moment of inertia of MR2.If m1 is 4.00 kg,m2 is 4.00 kg,M is 4.00 kg,and the angle is 70.0 degrees,then what is the acceleration of m1?
