7) Two masses, pulley, incline: Two blocks of mass M and m are connected by a light rope that passes over a frictionless pulley. Mass m has acceleration a up, and mass M has the same acceleration a down the frictionless incline, which has an angle of inclination of , as shown. (See PSL 5.2,5,9) a) Draw FBDs for each mass. b) Solve for (i) the normal force on M, (ii) the tension in the rope, and (iii) the mass m (all in terms of the other parameters given above). c) If M = 10.0 kg, a = 0.250 m/s/s, 0 = 30.0°, what are the values of (i) the normal force on M, and (ii) the tension, and (iii) the mass m?
