A 13004 N car traveling at 41.4 km/h rounds a curve of radius 2.28 × 102 m. The acceleration of gravity is 9.81 m/s2 . a) Find the centripetal acceleration of the car. Answer in units of m/s2 b) Find the force that maintains circular motion. Answer in units of N. c) Find the minimum coefficient of static friction between the tires and the road that will allow the car to round the curve safely.
A flat (unbanked) curve on a highway has a radius of 250 m
A flat (unbanked) curve on a highway has a radius of 250 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out. a. Draw free body diagram of the car. b. If the coefficient of static friction between the car's tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve without slipping? c. Suppose the coefficient of friction were increased...
