A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball? (Formula: )

Let's consider a scenario of a roller coaster ride. As the roller coaster at the top begins to descend, it loses height, which means its potential energy decreases and kinetic energy starts increasing and reaches its maximum value.By using the above scenario, which statement best compares potential and kinetic energy?
