At UPS, a sorting line is where boxes move from a horizontal belt to a stainless steel ramp then slide down the ramp to a bumper stopper where a person moves them to one of several conveyors depending on the destination. The boxes are moving at 1.2 m/s when entering the slide, which is 3 meters long and inclined at 20° degrees. How fast are the boxes moving when they hit the bumper?
