Height Speed Potential Energy Kinetic Energy Total Energy
6m 0 m/s² 4,704 Joules 0 Joules 4,704 Joules
3m 5.4 m/s² 2,352 Joules 2,352 Joules 4,704 Joules
0m 10.8 m/s² 0 Joules 4,704 Joules 4,704 Joules

2. At which height in the table, would the skateboarder have the greatest Kinetic Energy & Why?

Answer 1

The skateboarder would have the greatest kinetic energy at the height of 0m in the table. This is because kinetic energy is directly proportional to the square of the speed of an object. As the height decreases, the speed of the skateboarder increases due to the acceleration from the gravitational force, resulting in an increase in kinetic energy. At 0m height, the skateboarder has a speed of 10.8 m/s², which is the highest speed in the table, and therefore, the greatest kinetic energy.
