12. Rotational Kinematics / Types of Acceleration in Rotation / Problem 4
A toy car of mass 250 g is rolling on a circular vertical loop of diameter 1.0 m. The coefficient of kinetic friction between the car and the loop is 0.45. At the top of the loop, the speed of the car is 0.25 m/s. Determine the magnitude of the tangential acceleration at the top of the loop.
