A speed racer is driving very fast at 80 m/s in a straight line until it sees a cat crossing the road. The driver then puts on the breaks and the car slows down according to the relationship a = (-0.005v)m/s. The cat takes 17.5 s to move and runs away from the car (in the same direction) at 12 m/s. The cat is initially 50 m away. Show that the cat does not get hit by the speed racer. A speed racer is driving very fast at 80 m/s in a straight line until it sees a cat crossing the road.
