(10 pts) A 185 lb jogger is running at 8 mph. As he nears the end of his run, he decides to sprint, increasing his speed to 18 mph. How does his kinetic energy change? (Note: Express your answer as a multiple, e.g. his kinetic energy is 3 times as much, 72 as much, etc.)

In 2014, Damian Walters demonstrated that he could run through a vertical loop (after a lot of failed attempts). What minimum running speed did he need to do it? Assume the loop has a radius of 1.96 m, that Damian's mass is 76.5 kg, that he stays in contact with the loop at all times, and (unrealistically) that you can neglect friction and drag forces. Also, keep in mind that it's Damian's center of mass that matters, which is approximately...

The sport of skateboarding provides an excellent example of the principle of Conservation of Energy. In particular, let us consider 'vert skateboarding' where a personrides the skateboard on a vertical ramp that forms part of a hemisphere referred to as a 'half-pipe.' It consists of the transition from the curved part to the flatand the vertical. Below is a schematic of a half-pipe with the 'vert'. The surface of the half-pipe and the material of the wheels on the skateboard...
