| Have you ever followed a loaded dump truck in stop-and-go traffic? Not much fun! It's not much fun for Cuthbert, the truck driver either. All those people driving behind honking their horns and, you guessed it, cuthing!
Here's the info for this problem. It takes one full minute for Cuthbert's truck to accelerate from rest to 60 mi/hr but only 10 seconds to bring it back to a halt. As Cuthbert's truck gradually accelerates to highway speed, he tries to remember what he learned in physics about work and energy. Is more work done on the truck in bringing it up to speed or in bringing it to a halt? |
