1. The problem statement, all variables and given/known data A ball at the top of its drop has 15 J of potential energy, neglecting air resistance, what is the kinetic energy at the bottom of the drop? What is the velocity? 2. Relevant equations 3. The attempt at a solution Because the problem is asking for the kinetic energy and velocity at the bottom of the drop, I guessed that both the kinetic energy and velocity would be 0.
