A race track isconstucted such that two arcs of radius 35.0m and 70.0m are ateither end and joined by straight track. A driver, 70kg,travels a constant speed of 13.0m/s in a 1250kg car.
Find the conefficient of static friction between the tires andthe track on the 35.om curve?
Find the centripetal force the diriver feels around the 70.0mcurve?
Find the maximum speed the driver can take a car of 2000kg onthis same race track.
