The braking distance of a car is 29m. If the speed of the car is increased by 45%, what is the car's new braking distance? Assume the acceleration of the car is constant and independent of its initial speed

The braking distance of a car is directly proportional to te square of it's speed. When the speed is p metres per second, the braking distance is 6m. When the speed is increased by 300%, find (a) an expression for speed of the car

To stop a car, you require first a certain reaction time to begin braking. Then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 56.7 m when its
