10. DETAILS MY NOTES ASK YOUR TEACHER A tire is tied to a rope that is tied to the branch of a tree so that the tire swings in a circular trajectory of radiush, = 15.75 m. A child takes the tire to the top of a platform that is a height h, = 12.80 m above the ground, sits in the tire, and swings from rest from the platform. The combined mass of the tire and child is 40.3 kg. The rope is taut when the child leaves the platform and you may neglect the mass of the rope. At the bottom of the circular trajectory, the child and tire are a height h, = 0.85 m above the ground. , you must include a diagram showing the physical situation. (a) Calculate the speed of the child/tire at the bottom of the circular trajectory. m/s (b) Calculate the maximum tension in the rope as the child/tire swing back and forth. N h2

AP Classroom Unit 5.1 Torque Farouq Known iMass Unknown Mass 3 m- Fulcrum An experiment is performed by placing a known mass with its center of mass a distance of 3 meters from a fulcrum, as shown above. An unknown mass is used to balance the system, with its distance from the fulcrum not completely measurable. Every time the known mass is changed, the unknown mass is moved until equilibrium is reached. The data that were gathered for this experiment are below.

TEXT ANSWER Question 22 When Jenny couldn't lift a box by herself, she decided to use a lever to move it. She placed a fulcrum 1.6 m away from the box and used a 2.0 m lever to try to lift the box. Her effort was still unsuccessful. Explain why Jenny was unable to lift the box with her lever, and sug- gest a way she can adjust the lever to improve her chances of success. Use math to support your answer.
