1. Function project1b should NOT call makeBoard

  2. Is the magnitude just the absolute value of an x velocity or y velocity or is it the x and y velocities combined?


    3. Magnitude is the combined x and y velocities, but you cannot simply add the two. Think of the magnitude as the hypotenuse of a right triangle where the base is the x velocity and the height is the y velocity. 
               |\
           | \
y velocity |  \ magnitude
           |   \
           |    \
           ------
             x velocity
    Thus to calculate magnitude you can use the Pythagorean theorem:
    magnitude = square root of the sum of xVelocity squared and yVelocity squared
