Word Problem, math.
A police car traveling 100 ft/sec is chasing a car being driven erratically at 75 ft/sec. If the police car is 300 feet behind the other vehicle when the chase began, about how many seconds will it take to catch the erratic driver? I think I know how to solve this, but I want ...

The stopping distance of a car after the brakes are applied varies directly as the square of the speed r. If a car traveling 80 mph can stop in 360ft, how many feet will it take the same car to stoop when its traveling 50 mph?

Consider again the problem of a car traveling along a banked turn. Sometimes roads have a "reversed" banking angle. That is, the road is tilted "away" from the center of curvature of the road. If the coefficient of static friction between the tires and the road is μs = 0....
