3. A box of mass m1 125 kg rests on a surface inclined at 0 = 37° to the horizontal. It is connected by a lightweight cord, which passes over a frictionless pulley (M = 10 kg, R=10 cm), to a second box of mass m2 = 20 kg, which hangs freely as shown. The contact between mass m, and the incline is smooth. The system is released from rest and accelerates. Using rotational dynamics, determine the tension T2 in the vertical portion of the cord.
