An 18-cmcm-long bicycle crank arm, with a pedal at one end, is attached to a 20-cmcm-diameter sprocket, the toothed disk around which the chain moves. A cyclist riding this bike increases her pedaling rate from 60 rpmrpm to 92 rpmrpm in 15 ss. Assume constant angular acceleration. a)What is the tangential acceleration of a tooth on the sprocket? Express your answer with the appropriate units
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
