Question
5) At the Istanbul, Turkey Formula-One (F-1) race circuit, F.1 race cars routinely maintain speeds of 265 km/hr when rounding turn number 8 on the circuit, where this tough turn is called, "Diabolica" When going around this turn, the race car drivers experience large lateral accelerations, with average values of 5 gs where these large g-forces last for approximatety 7 seconds Assume that the cars execute uniform circular motion at constant radius when rounding Diaboica Calculate the radus of Diabolic in meters Choose the closest answer from those provided Select one O a 82 m O b. 124 m, or O c. 55 m O d 168 m
Explanation / Answer
Accleration=v*v/r
v=265 km/hr=73.6 m/s
5g=73.6*73.6/r
We got
r=110.5 m
So radius will be equal to 110.5 m
