32.3 kg block (m1) is on a horizontal surface, connected to a 5.70 kg block (m2) by a massless string as shown in the Figure below. The frictionless pulley has aradius R = 0.089 m and a moment of inertia I=0.140 kgm2. A force F = 216.9 N acts on m1 at an angle theta = 29.9°. There is no friction between m1 and the surface. What is the upward acceleration of m2?
