a car speeds over a hill past point a, as shown in the figure. what is the maximum speed the car can have at point a such that its tires will not leave the track of the curvature is 41.8?
Answers
Answer:
radius 18.0 m. At the top of the hill, she notices that she barely remains in contact with the seat. Find the speed of the vehicle.
(4 ed) 6.2 A car rounds a banked curve as in Figure 6.5. The radius of curvature of the road is R, the banking angle is , and the coefficient of static friction is .
(a) Determine the range of speeds the car can have without slipping up or down the road.
(b) Find the minimum value formu such that the minimum speed is zero.
(c) What is the range of speeds possible if R = 100 m, = 10o, and = 0.10 (slippery conditions)?
Conceptual Questions
Q6.4 Why does mud fly off a rapidly turning automobile tire?
For mud to move in a circle, there must be a (net) force on it -- directed toward the center of the circle. The value of that force is Fc = m v2/ r. As the velocity (or speed) increases, that force must increase if the piece of mud is to continue to move in a circle. As the velocity increases, the force that holds the mud to the wheel reaches its limit and the mud can no longer go around in a circle. When that limit is reached, the mud separates from the tire.
