The uniform solid block in the figure has mass 40.4 kg and edge lengths a = 0.506 m, b = 1.35 m, and c = 0.0554 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation axis Number Units

A diver goes into a somersault during a dive by tucking her limbs. If her rotational kindetic energy is 100 J and her moment of inertia in the tuck is 9.0kgm2 , what is her rotational rate during the somersault?

A potters wheel rotates with an angular acceleration = 4at3 3bt2, where t is the time in seconds, a and b areconstants, and has units of radians per second squared. Theinitial position of the wheel is 0 and the initial angular velocityis 0. Obtain expressions for the angular velocity and the angular displacement of the wheel as a function of time.

A seesaw has length 10.0 m and uniform mass 10.0 kg and is resting at an angle of 30 with respect to the ground (see the following figure). The pivot is located at 6.0 m. What magnitude of force needs to be applied perpendicular to the seesaw at the raised end so as to allow the seesaw to barely start to rotate?

Given the disk and density in Problem 11, derive an expression for the rotational inertia of this disk around an axis at theedge of the disk and perpendicular to the disks surface.

A cylinder with rotational inertia I1=2.0kgm2 rotates clockwise about a vertical axis through its center with angular speed 1=5.0rad/s . A second cylinder with rotational inertia I2=1.0kgm2 rotates counterclockwise about the same axis with angular speed 2=8.0rad/s . If the cylinders couple so they have the same rotational axis what is the angular speed of the combination? What percentage of the original kinetic energy is lost to friction?
