An extra credit project, a physics student in desperate need of point agrees to ride his motorcycle at a constant speed of 15 m/s over a hilly road while sitting on a bathroom scale. The profile of the road is shown above. As he passes point A he observes the scale reading to be 500 N.

A. What will the scale read at point B and C?
B. What would speed need to be at point B for the scale reading to be zero?
C. What would happen if he were traveling the road for 25m/s?

Point B has the 40 m radius and point C has the 30 m radius?

Thank you!
