Review Constants i Periodic Table Ice skaters often end their performances with spin turns, where they spin very fast about their center of mass with their arms folded in and legs together. Upon ending, their arms extend outward, proclaiming their finish. Not quite as noticeably, one leg goes out as well Part A Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.0 kg mº and for arms and legs in is...
Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.

Problems 18-20 Information: Two ice skaters, male (blue) and female (red) hold hands (purple) as they swing in a U-shape (yellow). The length of their extended arms is 0.5 m and the radius of the U is 0.3 m. At the instant shown, the man skates with a velocity of 4 m/s to the right (+x), slowing at an acceleration of -0.3 m/s2 (so am points to the left, (-x)). Approximate the skaters as a rigid body system of two...
Two ice-skaters, whose masses are 45 kg and 75 kg, hold hands and rotate about a vertical axis that passes between them, making one revolution in 3 s.
