9. I am travelling along a flat highway at 60mi/hr (26.8 m/s). (a) If the coefficient of friction between road and tires on a rainy day is 0.113, what is the minimum distance in which the car will stop? (b) What is the stopping distance when the surface is dry and the coefficient of friction is 0.565?
5, Some of the funniest videos on the web involve motorists sliding uncontrollably on icy roads. Here let's compare the typical stopping distances for a car sliding to a stop from an initial speed of 10.0 m/s on a dry horizontal road, an icy hori- zontal road, and (everyone's favorite) an icy hill. (a) How far does the car take to slide to a stop on a hori- zontal roadi if the coefficient of kinetic friction is = 0.60, which...
An automobile is travelling at 45 m/s on a horizontal road. If the coefficient of static friction between the tires and the road is 0.12, find the minimum stopping distance of the car.
A car is traveling at 27.7 m/s along a horizontal road. The coefficients of friction between the road and the tires are μs-0.54 and μk-0.1. Calculate the distance the car travel before stopping if the car is braked hard with no antilock braking system so that the wheels lock? (Take g-9.81 m/s2. 2% of error will be tolerated in your answers.)
A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.
The radius of curvature of a highway exit is r = 49.5 m. The surface of the exit road is horizontal, not banked What is the minimum required value of the coefficient of static friction between the tires of the car and the surface of the road so that the car can safely exit the highway at a constant speed of 42.0 km/h without sliding?
A woman is driving her van with speed 50.0 mi/h on a horizontal stretch of road. (a) When the road is wet, the coefficient of static friction between the road and the tires is 0.102. Find the minimum stopping distance (in m). m (b) When the road is dry, μs = 0.598. Find the minimum stopping distance (in m). m
A 1,200-kg car is traveling on an icy horizontal road at 30 m/s. The maximum rate at which the car can decelerate without sliding on the ice is 1.2 m/s2; reaching this value will immediately result in sliding uncontrollably with a reduced sliding friction of 700 N. If the driver panics and slams hard on the brakes, then how far will the car slide before stopping? Answer in km.
