Hi,
I need help with the following problem.
A skater does a pirouette at the rate of 2.0 rev / second and then stop within 3/4 rev. Assume that the angular decceleration is constant and calculate its magnitude.
I tried to compute it but I found -18 rad/s[sup]2[/sup].
BUt the textbook gives -17 rad/s[sup]2[/sup].
Please can someone help me with this problem?
Thank you
B
