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 25.0 cm and a moment of inertia of ½ MR2. If m1 is 2.00 kg, m2 is 1.00 kg, M is 4.00 kg, and the angle is 60.0 degrees, then what is the acceleration of m1?
A) 3.98 m/s2 down
B) 3.27 m/s2 down
C) 3.15 m/s2 down
D) 2.94 m/s2 down
E) 1.64 m/s2 down
