[Other] - Theme TH To do this, he lowers his body 0.300 m and then accelerates through this distance by forcefully straightening his legs. That's almost like asking which woman weighs more, and leaving the question at that. There would be a normal force pointing up and mg pointing down. The car encounters a loop of radius R = 18.0 m at ground level, as shown. If the car goes over the top at just the right speed, gravity alone will supply the centripetal force. To learn more, see our tips on writing great answers. Riders feel as if they are pinned to the wall by a force something like the gravitational force.
