Two cars A and B have a velocity of 25 m/sec. in the same direction. A is 73.5 m. behind B when the brakes are applied to car B, causing it to decelerate at a constant rate of 3 m/sec2. V=25 m/s V=25 m/s a=-3 m/s2 A B -SB -SA- -73.5- O In what time will A overtake B? 2 How far will car A travel? O How far will car B travel?
