Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A block accelerates 3 m / s 2 down a plane in- clined at angle 27.0 . The acceleration of gravity is 9 . 81 m / s 2 . m k 3 m / s 2 27 Find k between the block and the inclined plane. 1. 0.166 2. 0.853 3. 1.289 4. 0.510 5. 0.148 002 10.0 points A block sits motionless on an inclined plane, held in place by friction. The plane could be tilted even more upwards and the block would remain motionless. M s Consider the following statements: I. The magnitude of the frictional force equals M g sin . II. The magnitude of the frictional force is less than M g sin . III. The magnitude of the frictional force is greater than s M g sin . IV. Static friction must vanish since the block is not moving. V. The magnitude of the frictional force equals s M g cos . VI. The magnitude of the frictional force is less than s M g cos ....
