As shown in the picture below, a 40-kg diver is positioned so that his radius of gyration is 0.4m as he leaves the board with an angular velocity of 5 rad/s (Position 1). What is the diver's angular velocity when he changes his pose to Position2, altering his radius of gyration to 0.2m? Position 1 Position 2 CAR
You have your bicycle upside down while you adjust the chain. The chain is wound around the rear wheels small gear, which has a radius of 4.0 cm. At the pedals, the chain is wound around the large gear, which has a radius of 11.0 cm. The radius of the rear wheel is 35.0 cm. You spin the pedals initially so they finish two revolutions in 1.0 s, starting from rest. Assume constant acceleration. (a) Find the angular acceleration of the rear wheel in rad/s2. (b) Find the magnitude of the total acceleration of a point at the edge of the small gear at the end of 1.5 s (the sum of the radial and tangential accelerations). (c) What is the tangential acceleration for that point during the first second? (d) Calculate the linear acceleration of the chain.
In a conceptual design, the power to move a bus comes from the energy stored in an onboard rotating flywheel. The flywheel has a mass of 1500 kg, a radius of gyration of 500 mm, and is brought to a maximum speed of 4000 rpm. If the bus starts from rest and acquires a speed of 72 kph at the top of a hill 20 m above the starting position, find the reduced speed of the flywheel. Assume 10% of the energy of the flywheel is lost due to frictional effects. Neglect the energy of the bus contained in the rotation of the wheels. The bus with flywheel is 10,000 kg.

The uniform rod of mass M and length L rotates in the plane of the figure about an axis through one end. As the rod swings through its lowest position, it collides with a putty wad of mass m, that sticks to the end of the rod. If the rod's angular speed just before collision is w, a) what is the angular speed of the rod-putty system immediately after collision? Rotation axis Rod b) What is the change in the kinetic energy of the rod-potty system (immediately before to immediately after the collision)? Does the kinetic energy increases, decreases, or remains the same? Provide your answers symbolically.
A Lazy Susan (M=0.5 kg) in the shape of a disk is free to rotate about its center withoutfriction. It is initially motionless when a Texas-sized cockroach (m=10 g) starts runningCCW along the rim. The angular speed of the Lazy Susan is then 1 rad/sec. With whatspeed is the cockroach running (in the rest frame of the table, not the Lazy Susan)? (What more data should be given according to you? If the question seems incomplete to you...)
