Starting from a state of no rotation, a cylinder spins so that any point on its edge has a contant tangential acceleration of 3.1 m/s2. You keep track of the fractional number of turns N1 made made after 2.9 s and then that N2 made after 10 s. (Those numbers do not have to be integers.) What should be the approximate ratio N2/N1 ?
