2. A wheel of radius 15 cm accelerates uniformly from 100. rpm to 300. rpm in 8.0 sec. If the wheel is rolling without slipping, how far does the wheel roll in the 8.0 seconds? What is the linear acceleration of the axle of the wheel. What is the total acceleration of the top of the wheel when the wheel is rotating at 100. rpm?
An early method of measuring the speed of light makes use of a rotating slotted wheel. A beam of light passes through one of the slots at the outside edge of the wheel, travels to a distant mirror, and returns to the wheel just in time to pass through the next slot in the wheel. One such slotted wheel has a radius of 7.0 cm and 400 slots at its edge. Measurements taken when the mirror was 500 m from...
