You have just been given the assignment to develop a new bicycle computer.
The specifications for the device are:
The computer is determine the following items:
The distance the bicyclist has gone.
The velocity of the bicycle.
The calories expended by the cyclist.
The length of time of travel.
The user should be able to do the following items:
Enter her/his weight.
View the distance traveled, the calories expended, and the time traveled.
Reset the distance traveled, the calories expended, and the time traveled.
The inputs to the computer are:
The number of revolutions of the front wheel.
A tilt sensor which returns the angle of the bicycle (0 = level, negative ==> down hill, positive ==> up hill.
Things to keep in mind are:
Calories = work = Force x the distance through which the force acts.
Force = mass x acceleration.
Assume a constant frictional acceleration of 5 ft/sec/sec is required for level cycling.
