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

  • Physics -

    The time required to stop is proportional to the initial kinetic energy, and therefore proportional to V^2.

    The new braking distance will be higher by a factor (1.45)^2,.
