The speed of a baseball is measured as a function of time with a radar gun that has an accuracy of ±0.5 mph, and the time is known to ±0.02 s. If the average speed of the baseball is 90 mph and the average drag coefficient is 0.3, what is the uncertainty in the calculated value of the drag coefficient? (See Appendix D for information on propagation of errors in calculations.) You can assume that errors in measuring the air density and the diameter of the baseball are negligible.
