At a Grand Prix, drivers sustain lateral accelerations (sideways) about five times the acceleration due to gravity while driving around curves at speeds of 288 km/h. Assuming a circular curve, find the radius of that section of the track.

Answer 1

v^2 / r = 5 g

r = v^2 / (5 g)

r = (288 km/h)^2 / 49 m/s^2

r = (80 m/s)^2 / 49 m/s^2
