If I want a water balloon to hit the ground with 584 J of kinetic energy how high must I drop a 300 g balloon (0.3 kg) from to achieve this on Earth?

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.
