Answer to Question #259102 in Physics for Martin

Question

Solve the problem

A Ferris wheel with radius 15.0 m is turning about a horizontal axis through its center; the linear speed of the passenger rim is constant and equal to 9 m/s.

What are the magnitude and direction of the acceleration of a passenger as she passes through the lowest point in her circular motion?

How much time does it take the Ferris wheel to make one revolution?

Answer 1

$$a=\frac{9^2}{15}=5.4\frac{m}{s^2}$$

Upwards.

$$t=\frac{2\pi (15)}{9}= 10.5\ s$$
