Piecewise functions are sometimes useful when the relationship between a dependent and an independent variable cannot be adequately represented by a single equation. For example, the velocity of a rocket might be described by

Develop a well-structured function to compute v as a function of t. Then use this function to generate a table of v versus t for t 5 25 to 50 at increments of 0.5.
