Help me please

13. A racetrack surface has the shape of an inverted cone on which cars race in horizontal circles. What does a driver's speed have to be if she wishes to stay on a circular path without friction? You'll need to use trigonometry to get the angle of the racetrack. You also need to find the value of the radius r (that is, the distance from the car to the cone's axis). h= 5/4 m 10= 87 m A. 29 m/s B. 23 m/s C. 32 m/s D. 17 m/s
