The racing car travels with a constant speed of 240 km/h around the elliptical race track. Determine the acceleration experienced by the driver at B.
Answer
5/9 m/s^2
Explanation
Solution
The car moves at a constant speed on an elliptical track, so only centripetal acceleration is present. The given equation was corrected to represent an ellipse based on the problem description and diagram. The radius of curvature at point B (an endpoint of the minor axis) was calculated using the ellipse parameters. Finally, the centripetal acceleration was determined by dividing the square of the speed by the radius of curvature after converting units to SI.
