The skater's arms are fully extended during the jump. What is the approximate centripetal acceleration of the skater's hand?

A. \(10 \mathrm{~m} / \mathrm{s}^{2}\)

B. \(30 \mathrm{~m} / \mathrm{s}^{2}\)

C. \(300 \mathrm{~m} / \mathrm{s}^{2}\)

D. \(450 \mathrm{~m} / \mathrm{s}^{2}\)

Concern a classic figure-skating jump called the axel. A skater starts the jump moving forward as shown in Figure Q7.25, leaps into the air, and turns one-and-a-half revolutions before landing. The typical skater is in the air for about \(0.5 \mathrm{~s}\), and the skater's hands are located about \(0.8 \mathrm{~m}\) from the rotation axis.
