SUMMARY
The discussion centers on solving a physics problem involving a 1-ton rollercoaster descending from a height of 100 meters and reaching a speed of 20 m/s, assuming no friction. The key concept utilized is the conservation of energy, which states that the potential energy at the top converts to kinetic energy as the rollercoaster descends. By applying the formula for gravitational potential energy (PE = mgh) and kinetic energy (KE = 0.5mv²), the height above the ground when traveling at 20 m/s can be calculated definitively.
