In the Figure we show a car ridding around in a circle in a banked highway. In this situation a car is basically driving around in an inclined plane. The radius the car is making is 50 m, the angle of the inclined plane is 30°, and the coefficient of static friction between the road and the tires of the car is 0.5. What is the maximum speed a car can have so that it wont slide up the inclined plane as it is going around in a circle? DRAW A FREE-BODY DIAGRAM FOR THIS SITUATION IN THE FIGURE BELOW. Answer: 27.2 m/sec C Ө C Ө

Assume the speed of the object is constant Find the speed of the object in m/s Find the force applied to the object by the bar at the top of the circle (mag and direction) Find the force applied to the object by the bar at the bottom of the circle. ( mag and direction)
Centrifugal force is not a real force. It is the sensation you feel while traveling in a circle and your body’s inertia wants to go in a straight line. False Both true and false depends on the situation True Lack of information, the value of the centripetal force is not given
A car is moving on a banked curve at a speed v. A car is moving on a circular (radius = R) banked track (banking = B = 10° with respect to the horizontal) at a constant speed, v, in a circular path of radius R. A normal force, n, is exerted on the car from the track. The centripetal force is equal to the total normal force 0000 the radial component of the normal force the vertical component of the normal force none of the above
