1) a) An old wheat-grinding wheel in a museum actually works. The sign on the wall says that the wheel has a rotational acceleration of 190 rad/s^2 as its spinning rotational speed increases from zero to 1500 rpm. How long does it take the wheel to attain this rotational speed? Express your answer with the appropriate units. 1) b) The speedometer on an automobile measures the rotational speed of the axle and converts that to a linear speed of the...

The speedometer readings in passenger cars are based on angular speed of the car's tire axle. Because car's tires are filled with air [typically to the pressure of about 30 psi (pounds-square-inch)], the actual tire radius can be a bit different depending on the air temperature. You want to understand the impact of the air temperature on the tire radius and thus on the accuracy of the speedometer reading based on the ideal gas law. To simplify the calculation, you...
