A 47 kg skier rolls off from a frictionless slope with an inclination of approximately 400. From the bottom of the slope, she slides at 25 m/s until she stops 12 seconds later. Find
the coefficient of kinetic friction
at which point from the foot of the slope is the skier’s speed half the original speed?
Suppose that the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in the previous part. What should be the maximum speed of the car so it can round the curve safely?
The curved section of a horizontal highway is a circular unbanked arc of radius 520 m. If the coefficient of static friction between this roadway and typical tires is 0.30, what would be the maximum safe driving speed for this horizontal curved section of highway?
