A “back tuck” is a back flip in which the gymnast pulls in her legs in order to move more quickly. Suppose a gymnast with a rotational inertia of 16.0 kg m2/s begins rotating with an angular velocity of 6.0 rad/s. What new value of rotational inertia will she need to reach, in order to complete three-quarters of a rotation in half a second?

Two disks are rotating about the same axis. Disk A has a moment of inertia of 6 kg · m2 and an angular velocity of +10 rad/s. Disk B is rotating with an angular velocity of –4 rad/s and has a moment of inertia of 4kgm2. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit. The axis of rotation for this unit is the same as that...

A student sits in a chair that can spin without friction. The student has her hands outstretched and starts rotating at 1.7 rev/s. Her initial rotational inertia about the central axis is 13.00 kg m2. She pulls her hands inward and decreases her rotational inertial to 7.60 kg m2. What is her resulting angular speed after she pulls her hands inward?(rad/s) (in rad/s) What is the ratio of the new kinetic energy of the system to the original kinetic energy?  ...

Please answer all parts. Thank you! 1. Explain the correspondence that lets us easily translate between linear motion and rotational motion. What are the linear analogues of the rotational quantities we have discussed in lecture i.e. angle, angular velocity, angular acceleration and moment of inertia? Where does the correspondence seem to fail? 2. Explain, in words, how we know that a freely spinning asteroid in space is rotating about an axis that passes through its center of mass? 3. You...

A thin uniform rod has a length of 0.400 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.34 rad/s and a moment of inertia about the axis of 2.50×10−3 kg⋅m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end of...
