4. [Taylor 2.1* (tweaked)] When a beach ball flies through the air, the ratio fquad/flin of Squad the quadratic to the linear drag force is given by flin B = LDv = (1.6 X 103 Dv m (2.7). Given that a beach ball has diameter 70 cm, find the approximate speed v at which the two drag forces are equally important. Comment on the results and compare them to the behavior of the baseball as discussed in lecture. Setup the Problem: List given information, define variables and coordinate system, sketch picture. Simplify question: Restate the question in simpler terms and list target quantity Obtain a general solution (attach more sheets if needed) Check units: Does solution have appropriate units? Test a limiting case: Explain the test and see if it works as expected
