10. A m₁ = 3.00 kg object and a m₂ = 12.0 kg object are joined by a cord that passes over a pulley with a radius R = 10.0 cm and a mass M-3.00 kg. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest. Treating the pulley as a uniform disk (TMR²) (a) (2 pts) draw a free-body diagram for mi (b) (3 pts) draw a free-body diagram for m₂ (c) (3 pts) draw a free-body diagram for the pulley. (d) (4 pts) write the Newton's second law for my (FNET.y = may) (e) (4 pts) write the Newton's second law for m₂ (FNETxmay, FNETY = may) (f) (4 pts) write the equation for the pulley (TNET = la) (g) (4 pts) Solve for T₁, T₂, and a (the tensions in the cord and the acceleration of the masses).
