A car of mass 772 kg is traveling 24.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.27 s in the positive x-direction before coming to rest.
a). What is the car's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.)
b). What magnitude force (in N) acted on the car during this time?
c). How far (in m) did the car travel?

A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...

The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 4.85 m/s2. If the car's initial speed is 28.5 m/s, how long does it take to stop and how far does it travel, starting from the moment the brakes are applied? time to stop? stopping distance?
