PSYW - Please Show Your Work Mac and Tosh are on a roller coaster ride and moving rapidly over the crest of a small
hill. The hilltop has a curve that resembles a section of a circle with a radius of 40
meters. The speed of the 470-kg roller coaster car at the crest is 15 m/s.

Determine the acceleration (in m/s2), net force (in N), and the magnitudes of all
individual forces when the car is at the crest.
Finally, indicate the direction of the net force and acceleration. Use g = 9.80 m/s2
