A ball is raised to a height of 30.0m above the ground. What would its velocity be when it has fallen to a height of 15.0m above the ground. (You must solve this as a conservation of energy problem, and can do it in one step!) Any help would be appreciated..

  2. gravitational potential energy becomes kinetic energy

    m g h = 1/2 m v^2

    v = √(2 g h) = √(2 * 9.81 * 15.0)
