| TURN IN 24, 48, 52 |
| 24. 1.4 N*m, clockwise |
| 48. (a) 8.37 m/s and 41.8 rad/s are the translational (CM) velocity and angular velocity, respectively (b) 2.5 (c) None of the results depend on the mass, which cancels out. Only the angular velocity depends on the radius . |
| 52. (a) 7.1 kg*m2/s (b) -1.2 N*m . The negative sign indicates the angular acceleration is negative and is oriented in the direction opposite the the actual rotation. In other words, the object slows down as it rotates until it comes to rest.. |
