A car was about to hit a cat and the driver suddenly hit the brakes, leaving a skid mark 50m long on the road. Assuming that the deceleration is 5.7 m/s2, what is the speed of the car just before breaking? What does deceleration means in this problem? Group of answer choices The car continues to move with constant velocity. The velocity of the car becomes zero and its acceleration is 5.7 m/s2 . No answer The car continues to move with decreasing velocity. The car continues to move with increasing velocity.
