In a "crazy elevator ride" at the amusement park, a 300 kg "elevator car" slides vertically down a frictionless shaft and curves onto a horizontal section, descending a total height of 25 m. On the horizontal section is a friction pad designed to bring the car to rest. If the coefficient of friction between the car and the pad is μk=0.4, how long in meters does the pad need to be to stop the car?
