MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 3000-pound automobile is negotiating a circular interchange of radius r = 400 feet at s = 30 miles per hour (see figure). Assuming the roadway is level, find the force between the tires and the road such that the car stays on the circular path and does not skid. (Use F = ma, where m = 3000/32. Round your answer to the nearest integer.) F = Ib .Find the angle at which the roadway should be banked so that no lateral frictional force is exerted on the tires of the automobile. (Round your answer to one decimal place.) Enter a number. Need Help? Read It Submit Answer Viewing Saved Work Revert to Last Response 36. [-/0.5 Points] DETAILS LARCALCET7 12.4.007.
