Doug is on a ferris wheel, which is spinning counterclockwise relative to you. The ride is over and the wheel is starting to slow down. What direction is his acceleration at the top of the ferris wheel?

Vertical circular motion
Practice: Vertical String
A box of mass 2.50 kg is attached to a string and whirled in a vertical circle of radius 1.0 m. At the exact top of the path, the tension in the string is 3 times the ball’s weight.
Ferris wheel
Practice: Ferris Wheel
A 65 kg man is riding a Ferris wheel with radius of 15 m, that moves at speed 2.355 m/s. Determine the normal force that the man experiences at the top of the ferris wheel and at the bottom.

Circular motion
A race car starts from rest on a circular track. The car increases its speed at a constant rate at as it goes once around the track in the counterclockwise direction. Find the angle that the total acceleration of the car makes with the radius of the circle, at the moment when the car completes first full circle.
A runner is running at a speed of 10m/s along a circular track of radius 25 m.
(a) Find the time it takes to complete one lap when he is running at constant speed.
(b) Find the radial acceleration during this time.
