A certain car traveling 24.0 mph skids to a stop in 28 meters from the point where the brakes were applied. In approximately what distance would the car stop had it been going 72 mph?
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 initially traveling at 33.5 m/s undergoes a constant negative acceleration of magnitude 1.40 m/s after its brakes are applied. (a) How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the tires have radil of 0.330 m? (b) What is the angular speed of the wheels when the car has traveled half the total distance? rad/s
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 initially traveling at 25.4 m/s undergoes a constant negative acceleration of magnitude 1.80 m/s2 after its brakes are applied.

(b) What is the angular speed of the wheels when the car has traveled half the total distance?
A car is 162 m from a stop sign and traveling toward the sign at 27 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
A car is 137 m from a stop sign and traveling toward the sign at 25 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
