A racecar driver has to hold on tightly when going around a banked curve. How many "gs" does the driver experience in a 2200 kg car going around a circle with a radius of 95 meters at 25 m/s?

Answer 1

v^2 / R is centripetal acceleration

divide that by g or about 9.81 m/s^2 to get the number of g s

Your question does not say if you are to include 1 g due to weight down.
If so it would be 1 g up and v^2 / gR inward
or sqrt (1 + v^2/gR)
