A solid sphere of radius 10 cm is allowed to rotate freely about an axis. The sphere is given a sharp blow so that its center of mass starts from the position shown in the following figure with speed 15 cm/s. What is the maximum angle that the diameter makes with the vertical?
A skateboarder with his board can be modeled as a particle of mass 76.0 kg, located at his center of mass (which we will study in Chapter 9). As shown in Figure P8.49, the skateboarder starts from rest in a crouch-ing position at one lip of a half-pipe (point ). The half-pipe is one half of a cylinder of radius 6.80 m with its axis horizontal. On his descent, the skateboarder moves without friction so that his center of mass moves through one quarter of a circle of radius 630 m. (a) Find his speed at the bottom of the half-pipe (point (b) Immediately after passing point he stands up and raises his arms, lifting his center of mass from 0.500 in to 0.950 m above the concrete (point ). Next, the skateboarder glides upward with his center of mass moving in a quarter circle of radius 5.85 m. His body is horizontal when he passes point , the far lip of the half-pipe. As he passes through point , the speed of the skateboarder is 5.14 m/s. How much chemical potential energy in the body of the skateboarder was converted to mechanical energy in the skateboarderEarth system when he stood up at point ? (c) How high above point does he rise? Caution: Do not try this stunt yourself without the required skill and protective equipment. Figure P8.49

The puck in Figure P11.46 has a mass of 0.120 kg. The distance of the puck from the center of rotation is originally 40.0 cm, and the puck is sliding with a speed of 80.0 cm/s. The string is pulled downward 15.0 cm through the hole in the frictionless table. Determine the work done on the puck. (Suggestion: Consider the change of kinetic energy.) Figure P11.46

Lily is a 50 kg diver. At the instant of takeoff, her angular momentum about her longitudinal axis is 20 kgm2/s. Her radius of gyration about the longitudinal axis is 0.4 m at this instant. During the dive, Lily tucks and reduces her radius of gyration about the longitudinal axis to 0.2 m. At takeoff, what is Lily’s moment of inertia about her longitudinal axis? At takeoff, what is Lily’s angular velocity about her longitudinal axis? After Lily tucks, what is her moment of inertia about her longitudinal axis?

You and some fellow physics students decide to investigate the concept of moment of inertia foryourselves. You set up an experiment in which you race a number of similarly sized objects down africtionless ramp. The angle of the ramp is  = 20 and the distance the objects slide or roll down theramp is s = 1 m. All the objects are made out of the same type of steel and so are of uniform density.The objects you have are: 1) a solid cube measuring 5 cm on a side and having a mass of 0.98 kg; 2) asolid sphere of 2.5 cm radius and having a mass of 0.52 kg; 3) a hollow sphere with an outer radius of2.5 cm, an inner radius of 1.25 cm, and a mass of 0.45 kg; 4) a spherical shell of 2.5 cm radius and 0.06kg mass; 5) a solid cylinder having a radius of 2.5 cm, a length of 5 cm, and a mass of 0.77 kg; 6) ahollow cylinder of 2.5 cm outer radius, 1.25 cm inner radius, 5 cm length, and 0.58 kg mass; and 7) andtube (cylindrical shell or ring) having a radius of 2.5 cm, a length of 5 cm, and a mass of…

An ice skater starts a spin with her arms stretched out to the sides. She balances on the tip of one skate to turn without friction. She then pulls her arms in so that her moment of inertia decrease by a factor of three. In the process of her doing so, her kinetic energy __________ by a factor of ______
Multiple choice: Which of the following happens to angular velocity when a diver moves from a tuck position to a layout position? A. Angular velocity decreases because angular momentum must be conserved B. Angular velocity is conserved because angular momentum decreased C. Angular velocity increases because angular momentum must be conserved D. Angular velocity is conserved because angular momentum increased E. None of these is correct; body position has no impact on angular velocity
