Sharon asks…If the speed of a car is increased by 55%?If the speed of a car is increased by 55%, by what factor will its minimum braking distance be increased, assuming all else is the same? Ignore the driver's reaction time.
_____Nancy answers:Using the work energy theorem:
Ki + W(friction) = Kf
W(friction) = F(friction) * d, distance travelled times the force of friction, this will be negative since the friction vector is pointing opposite of direction of motion.
We know that the car stops
