Exercise 12

In performing a "figure 8" maneuver, a figure skater wants to make the top part of the 8 approximately a circle of radius 2.20 m. He needs to glide through this part of the figure at approximately a constant speed, taking 4.50 s. His skates digging into the ice are capable of pro-viding a maximum centripetal acceleration of 3.25 m/s 2. Will he be able to do this as planned If not, what adjustment can he make if he wants this part of the figure to remain the same size (assume the ice conditions and skates don't change)
