In the Soap Box Derby, kids build non-motorized cars with very low-friction wheels. They race by rolling down a hill. The track at Akron's Derby Downs begins with a 14-meter section tilted 15 degrees below the horizontal. A. Draw a useful pictorial representation for this problem. Clearly indicate the angle above, and a useful coordinate system. B. What is the acceleration of a car rolling down this hill (ignore friction)? C. If a car starts from rest at the top of the section so that will be its speed at the bottom of this section of the track?
