Unformatted text preview: ECE 1574 Homework Set #3 Engineering Problem Solving with C++ Due date: 2/7/10 by 11:55PM Beware of the Super Bowl time sink on Sunday This assignment is to be done individually Solve problems 2, 3, 4, 5, 6, and 7 during the lab session. Work the additional exercises later. Potentially useful information: The cmath library provides the function atan2( double y, double x ), which returns the arctangent of the ratio y/x, where y is a rise and x is a corresponding run. The arctangent of 1.0/1.0 is 45 degrees, which in radians is /4. This fact implies one good way of getting the computer to calculate the value of . Problem 1 Use Einsteins mass-energy equivalency to determine the energy of a mass of 5, 10, and 20 kilograms. Perform your calculations using integers and a second set of calculations using float values. Explain why the two sets of results are different. What are the units of energy?...
