Homework Answers
At high speeds, the friction force acts down the incline plane, and
At low speed, the friction force acts up the inclined plane.
Therefore,
Answer : It depends on the speed at which you drive.

A curve on a road has a radius of curvature of 500.0m and is banked at an angle of 10.00 degrees, if a 1700.0Kg car is traveling at a speed of 27.0m/s around the curve, what is the magnitude and direction of the static frictional force needed to keep the car around the curve at this speed?

1) A road is banked at 10 degrees at a circular turn of radius 100m. a. What is the exact speed required such that the car stays on the road when it is icy and without friction? b. What minimum coefficeient of static friction is needed if the car travels at exactly one half the speed you found in a.

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

A toy car of mass 0.35 kg travels along a circular banked road, with banking angle 30°. The circle has radius 0.80 m. Sarah wants to make the car move as fast as possible, but if it goes too fast, it slips off the road. Therefore, Sarah cuts a 0.80- meter piece of string, attaches one end to the car, and attaches the other end to a nail stuck in the center of the circle. Unfortunately, the string is thin...

Brake or turn? Figure 6-45 depicts an overhead view of
a car's path as the car travels toward a wall. Assume that the
driver begins to brake the car when the distance to the wall is
d = 109 m, and take the car's mass as m = 1430
kg, its initial speed as v0 = 37.0 m/s, and the
coefficient of static friction as μs = 0.530.
Assume that the car's weight is distributed evenly on the four
wheels,...

You try drive a car with mass 470kg at 40km/h around a circular track of radius 30m. A) What is the centripetal force on required to hold the car in this circular B) The track is banked at an angle of 12 degrees. What size is the friction force preventing the car sliding up the slope? C) If there is a coefficient of maximum static friction of 0.01, can you make the turn or will your car skid?
