A car is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53.
(a) Find the acceleration of the car. (Take down the ramp to be the positive direction)
(b) How long does the car take to skid to a stop if its initial speed is 32 mi/h (14.30528 m/s)?

A car is traveling up a road inclined at an angle Theta above the horizontal. The driver slams on the brakes and skids to a stop. The coefficient of kinetic friction between the tires and the pavement for the car sliding to a stop is mu_k. Find an expression for the acceleration of the car as it slides to a stop. Using your result above, find the numerical value of the car's acceleration if Theta = 8.0 degree and mu_k...

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 (m = 2000 kg) is traveling down a 15 degree incline at 65 m/s. The driver slams on the breaks causing the wheels to lock. Omega_x = 0.3. How far S will the tires skid on the road? If the driver can skid only 10 m before hitting another vehicle, how fast will the driver hit the other vehicle?

A 1890 kg car traveling at 13.3 m/s collides with a 2970 kg car
that is initally at rest at a stoplight. The cars stick together
and move 1.96 m before friction causes them to stop. Determine the
coefficient of kinetic friction between the cars and the road,
assuming that the negative acceleration is constant and all wheels
on both cars lock at the time of impact.

Two cars are traveling in the same lane in the same direction. They are 120 ft apart and are both traveling at 60 mph. The roadway is level. The leading car hits a disabled milk truck and comes to an instatenous stop. The perception-reaction time of the driver in the trailing car is ½ second. The driver of the trailing car locks the brakes and skids into the lead car. The coefficient of friction between the roadway and skidding tires...

A 2170 kg car traveling at 12.2 m/s collides with a 2940 kg car that is initally at rest at a stoplight. The cars stick together and move 2.02 m before friction causes them to stop. Determine the coefficient of kinetic friction between the cars and the road, assuming that the negative acceleration is constant and all wheels on both cars lock at the time of impact.

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...
