18 POINTS Luther is designing a roller coaster for an amusement park. At one point, the roller coaster will enter a horizontal loop at a speed of 31.8 m/s. If Luther does not want the centripetal acceleration to exceed 29.0 m/s2 , what is the minimum radius of the horizontal loop?

Answer asap ! the shortest path from point a to point b goes through a pond. to avoid the pond, you must walk straight 34 meters along one edge of the pond, then take a 90 degree turn, and again walk straight 41 meters along another edge of the pond to reach point b. about how many meters would be saved if it were possible to walk through the pond? a. 11 m b. 20 m c. 30.45 m d. 21.73 m
