When a pendulum swings in a small arc, the magnitude of the acceleration tangent to O 1. changing direction the arc at one end of the path is O 2. in a direction perpendicular to the path O 3. a minimum O 4. a maximum 5. zeroIn the image below, four identical pucks slide across a frictionless surfaces. All pucks O 1. Path 3 have the same initial, horizontal velocity vo. For paths 1-3, the pucks remain in contact with their surfaces throughout the motion. O 2. Path 2 For path 4, the puck slides off the edge, but does not bounce when it hits the surface be- low. Finish 3. Path 2 & Path 4 path 1 4. Path 3 & Path 4 path 2 path 3 5. None of the other pucks reach the finish at the same time as the puck traveling along Path 1. path 4 O 6. All pucks reach the finish at the same time The puck which moves along path 1, reaches the finish line in a time t1. O 7. Path 2 & Path 3 Which of the other pucks also reaches the finish line at the same time as the puck which moves along path 1? 8. Not enough information O 9. Path 4
