A mass m1 = 6.4 kg rests on a frictionless table. It is connected by a massless and frictionless pulley to a second mass m2 = 3.3 kg that hangs freely. 1) What is the magnitude of the acceleration of block 1? 3.33 m/s² submit + 2) What is the tension in the string? 21.35 Submit 3) m Now the table is tilted at an angle of 0 = 75° with respect to the vertical. Find the magnitude of the new acceleration of block 1. m/s2 Submit + 4) At what "critical" angle will the blocks NOT accelerate at all? Submit 5) Now the angle is decreased past the "critical" angle so the system accelerates in the opposite direction. If 0 = 31° find the magnitude of the acceleration. m/s Submit
