certain car traveling at 97 km/h can stop in 46 m on a level road. Determine the coefficient of friction between the tires and the road. Assume that the car starts skidding the moment the driver hits the brakes.

An object moves with an initial speed of 5.01 m/s. It then enters a region with friction causing the object to come to rest after moving 2.56 m. What is the coefficient of friction?

A 2000 kg trailer truck travels down a road with slope 0.2 with a speed of 20 kph. If the truck driver pressed the brakes hard, determine how far the tires skid on the road if the coefficient of kinetic friction between the wheels and the road is 0.6.

A man is driving his car with speed 47.0 mi/h on a horizontal stretch of road. 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). When the road is dry, ?s= 0.603.  Find the minimum stopping distance (in m).

A box slides along a horizontal floor with an initial speed of 2.5 m/s. It comes to rest after sliding 1.4 m. Find the coefficient of kinetic friction. (g=9.8 ms-2 )

An automobile is going up a grade of 15 with an initial velocity of 30 m/s. The coefficient of static friction between the tires and the road is 0.7. a) What minimum distance does it take to stop the car? b) What minimum distance would it take to stop the car if it were going down the grade?

A car is driving along a circular track with diameter d = 0.59km at a constant speed of v = 21.2 m/s.  Write an expression and find the value for the minimum coefficient of friction between the cars tires and road required in order to keep the car going in a circle in terms of the given parameters.

The box below has been given an initial velocity of 2.60 m/s directed up the ramp. The angle the incline makes with the horizontal is 34.0°. The coefficient of static friction between the box and the ramp is 0.430 while the coefficient of kinetic friction between the box and the ramp is 0.280. Use g = 9.80 m/s2. (a) Calculate the magnitude of the box's acceleration while it is sliding up the ramp. m/s2 (b) How far (measured parallel to the incline) does the box travel before coming instantaneously to rest? m (c) After the box comes instantaneously to rest on the ramp, it then either starts sliding down, or remains at rest. Either enter 0, if you determine that the box remains at rest, or calculate the magnitude of the box's acceleration while it is sliding back down the ramp. m/s2

Determine the maximum theoretical speed that may be achieved over a distance of 110 m by a car starting from rest assuming there is no slipping. The coefficient of static friction between the tires and pavement is 0.75, and 60 percent of the weight of the car is distributed over its front wheels and 40 percent over its rear wheels. Assume (a) front-wheel drive, (b) rear-wheel drive.

A car with a mass of 1.3x10° kg is skidding to a stop along a horizontal surface. The car decelerates from 33 m/s to rest in 3.9 seconds. Assuming negligible air resistance, determine the coefficient of friction between the car tires and the road surface.
