A 32.7-kg block (m1) is on a horizontal surface, connected to a 6.7-kg block (m2) by a massless string as shown in the Figure. The pulley is massless and frictionless. A force of 236.1 N acts on m1 at an angle of 28.7o. The coefficient of kinetic friction between m1 and the surface is 0.245. Determine the upward acceleration of m2.
