A certain car traveling at 15.2 m/s skids to a stop in 29 meters from the point where the brakes were applied. In approximately what distance would the car have stopped had it been going 51.2 m/s?

Newtons laws of motion

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

Your answer would be the sun
