You are advising a fellow student who wants to learn to perform multiple flips on the trampoline. You have him bounce vertically as high as he can, keeping his body perfectly straight and vertical. You determine that he can raise his center of mass by a distance of h = 6.00 m above its level when he initiates the jump. He can do a single flip by bouncing gently, throwing his arms forward over his head, and tucking his body. You use your smartphone to make a video of him doing a single flip. Based on analysis of this video, you determine that his moment of inertia is Istraight = 26.7 kg . m2 when his body is straight and Ituck = 5.62 kg . m2 in the tuck position. You suggest that he keep his body in the straight position for Δt, = 0.400 s after leaving the trampoline surface and then immediately go into a tuckposition. As he lands, he should straighten his body out Δt, = 0.400 s before he lands. From analysis of the video recording, you determine that throwing his arms forward causes…
Masses A (1.00 kg) and B (2.00 kg) are attached to opposite ends of a light rod 1.00 m long that is mounted on a frictionless, horizontal axle through the midpoint. The rod is initially horizontal. Find the speed of the masses as the rod swings to a vertical position. Draw and label any diagrams.
Alice and Bob are standing at the middle of a level, perfectly balanced seesaw. Alice has a mass of 40 kg
and Bob has a mass of 50 kg. If Alice starts to walk at 1m/s away from the center of the seesaw while
remaining on it, how fast should Bob walk so that the seesaw remains level? If you do not know what a
seesaw is, feel free to use your computer to search online for illustrations.

- A solid cylinder and a hollow cylinder have the same mass, same radius, and turn on frictionless, horizontal axles. (The hollow cylinder has lightweight spokes connecting it to the axle.) A rope is wrapped around each cylinder and tied to a block. The blocks have the same mass and are held the same height above the ground as shown. Both blocks are released simultaneously. The ropes do not slip. Which block hits the ground first? Or is it a tie? Explain.arrow_forwardA 90 kg man stands in a very strong wind moving at 14 m/s at torso height. As you know, he will need to lean in to the wind, and we can model the situation to see why. Assume that the man has a mass of 90 kg, with a center of gravity 1.0 m above the ground. The action of the wind on his torso, which we approximate as a cylinder 50 cm wide and 90 cm long centered 1.2 m above the ground, produces a force that tries to tip him over backward. (Drag coefficient for the cylinder in this position is Cp 1.1.) To keep from falling over, he must lean forward. What is the magnitude of the torque provided by the wind force? Take the pivot point at his feet Assume that he is standing vertically. Assume that the air is at standard temperature and pressure Express your answer with the appropriate units.

The ramp is 1 m long, and is elevated at an angle of 15°.
