15. A 1500-kg car making a turn on a dry banked highway ramp with angle of inclination of 10 is experiencing friction. The coefficient of static friction between the tires and the road is 0.40. Draw vector components for the force of static friction and for the normal force. a. Determine the maximum speed at which the car can safely negotiate a turn of radius 2.0 102 m. (7 marks) b. How would this maximum speed be different if (3 marks) i) the car were heavier? ii) the angle were greater? the coefficient of friction were less?
