The skateboarder would have the greatest kinetic energy at the lowest point of their descent on a ramp or hill. This is because kinetic energy (KE) is given by the formula \( KE = \frac{1}{2} mv^2 \), where \( m \) is the mass of the skateboarder and \( v \) is their velocity. At the lowest point, the skateboarder accelerates due to gravity, achieving the highest speed, which maximizes the kinetic energy. Additionally, as they move up inclines, potential energy increases, leading to a decrease in kinetic energy if the total mechanical energy is conserved.
At which point in the image, would the skateboarder have the greatest Kinetic Energy & Why?
