A car is moving at 20.0 m/s when the driver sees a traffic light ahead turn red. The driver applies the brakes slowing uniformly to a stop. As the car slows to a stop, it travels a distance of 60.0m. A) Please draw an acceleration vs time graph. B) Please draw a velocity vs time graph. C) Please draw a position vs time graph.
1. John (who is 95 kg) drives his car over an absurdly large half-circle speedbump with a radius of 5 meters. Given that his normal weight is 930 N and his apparent weight at the top of the speed-bump was 246 N, how fast did he drive over the speed bump? 2. When working in circular motion problems, what do we define as always being the positive direction? 3. When in circular motion, the net force points in what direction?...
