Data from a skateboard stimulation.
1) Using speed and height, calculate the maximum possible height of the skater, using the energy conservation equation.
2) From the height and potential energy, calculate the mass of the skater. From the speed and kinetic energy, calculate the mass again.
Please show the equation and all steps!
Height: -1.41 meters
Potential Energy: -1035.34 Joules
Speed: 9.41 m/s
Kinetic Energy: 3320.10 Joules
3) At a speed of 8.65, would the speed change if the skater had twice the mass? Using the Conservation of Mechanical Energy equation to show how the speed at the bottom depends (or doesn’t) on mass.
4) How would the speed of the skateboarder change if he was in space?
