12. Rotational Kinematics / Types of Acceleration in Rotation / Problem 5
An 850 g toy sled glides in a circle on a bench (µk = 0.4) with the help of a 1.50 m long thread. A fan fitted on the toy thrusts air creating a 6.0 N force perpendicularly to the thread. The thread can withstand a force of 90 N before breaking. Starting from rest, determine the number of circles completed by the toy sled before the thread snaps.
