9. Two blocks are positioned on surfaces, each inclined at the same angle of 58.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 3.66 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.460. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? 2.16 kg 9.99 kg 6.02 kg 3.06 kg
Two masses, m, = 2.16 kg and m, = 9.71 kg are on a horizontal frictionless surface and they are connected together with a rope as shown in the figure.

5. Three nondescript boxes are hung from a rope and pulley system. The masses are: M1 = 6 kg, M2 = 3 kg. M3 = 4 kg. Assuming the pulley and ropes are perfect (no mass or friction), we will find the three tensions. a) Let's start by making four free body diagrams: one for each mass and one for the entire system represented as one big mass.

A mass of 2.0 kg is suspended from the ceiling of an elevator by a rope. What is the tension in the rope when the elevator (i) accelerates upward at 1.5 m/s2 ? (ii) accelerates downward at 1.5 m/s2 ? a. (i) 22.6 N; (ii) 16.6 N b. Because the mass is hanging from the elevator itself, the tension in the rope will not change in either case. c.

7. A mass m₁ = 5.00 kg is connected by a light string that passes over a pulley of mass m3 = 8.0 kg to a mass m2 8.50 kg sliding on a frictionless inclined surface that makes an angle of 23° with the horizontal (see figure).
