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?
