Q. A bicycle has wheels with a diameter of 0.67m. It accelerates uniformly and the rate of rotation of its wheels increases from 191 rpm to 260 rpm in a time of 21.70 s. Find the linear acceleration of the bicycle.
Q. Consider an excessively small space station that consists of a 3.9 m radius rotating sphere. A man standing inside is 1.9 m tall and his feet are at 1.00 g. What is the acceleration of his head?
