A section of a high speed test track is circular with a radius of curvature R = 1620 m.
At what angle of θ should the track be inclined so that a car
traveling at 65.0 m/s (145 mph) would keep moving in a circle if
there is oil on that section of the track, i.e., it would not slip
sideways even with zero friction on that section. (Hint: The car's
vertical acceleration is zero.)
