2) A car is traveling at 18 m/s on a horizontal highway. (a.) If the coefficient of friction between the road and the tires on an icy day is 0.10, what is the minimum distance in which the car will stop? (b.) What is the minimum stopping distance when the surface is dry and the coefficient of friction is 0.60?
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?
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 car is traveling at 55.0 mi/h on a horizontal highway. (a) If the coefficient of static friction between road and tires on a rainy day is 0.102, what is the minimum distance in which the car will stop? (b) What is the stopping distance when the surface is dry and ?s = 0.605?
A car is traveling at 53.0 mi/h on a horizontal highway. (a) If the coefficient of static friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop? m (b) What is the stopping distance when the surface is dry and µs = 0.604?
A car is travelling at 20m/s on a horizontal road. The brakes suddenly are applied and the car skids to a stop in 40 s with a constant acceleration. a) Draw a free body diagram for the car? b) Write newton's second law in the vector form and project it on the reference system. c) What is the coefficient of kinetic friction between the tires and road?
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 car is moving at 16 m/s along a curve on a horizontal plane with radius of curvature 49 m . The acceleration of gravity is 9.8 . What is the required minimum coefficient of static friction between the road and the car’s tires to keep the car from skidding?
It requires a stopping distance of 150 m to brake on a flat road from a speed of 22 m/s to rest with a particular set of brakes. (a) Find the acceleration of the car. (b) Find the coefficient of friction between the tires and the road. (You may assume the car has a mass of 1250 kg but that is NOT needed to solve the problem.)
Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 31.6 m radius?
