Question

Olympic ice skaters are able to spin at about 5 rev/s. (a) What is their angular velocity in radians per second?
(b) What is the centripetal acceleration of the skater's nose if it is 0.120 m from the axis of rotation?
(c) An exceptional skater named Dick Button was able to spin much faster in the 1950s than anyone since—at about 9 rev/ s. What was the centripetal acceleration of the tip of his nose, assuming it is at 0.120 m radius?

Final Answer

- $30 \textrm{ rad/s}$
- $1\times 10^{2}\textrm{ m/s}^2$
- $4\times 10^{2}\textrm{ m/s}^2$
