If the speed of a car is increased by 40%, by what factor will its minimum braking distance be increased, assuming all else is the same? Ignore the driver's reaction time. 2. Relevant equations K=1/2 m v^2 w=fd 3. The attempt at a solution well i set kenitic energy to work so i got 1/2mv^2 = Fd, the force acting on the car is friction i then rewrote equation to V^2 / (2MG) = D, i got about 1.4 when i set velocity mass and gravity to 1. Didnt show up correctly on my webassign any suggestions?
