Atire-pressure monitoring system warns you with a dashboard alert when one of your car tiresis significantly under-inflated. how does this pressure monitoring system work? many cars havesensors that measure the period of rotation of each wheel. based on the period of rotation, thecar’s computer determines the relative size of the tire when the car is moving at a certain speed.(a)derive a mathematical equation that relates the period t of the wheel rotation of the tireradius r and the speed v of the car.(b)the figure below shows a properly inflated tire (left) and an underinflated tire (right) ofthe same car. estimate the percent change of the period of the underinflated tirecompared to the properly inflated tire.
