Question

Computer-controlled display screens provide drivers in the Indianapolis 500 with a variety of information about how their cars are performing. For instance, as a car is going through a turn, a speed of 201 mi/h (89.847 m/s) and a centripetal acceleration of 4.00g (four times the acceleration due to gravity) are displayed. Determine the radius of the turn (in meters).

Answer 1

a=v²/r
a=4*9.81 m/s²
v=89.847 m/s
solve for r

Answer 2
