Problem

0.25\,\text{kg}

ball is released from rest at the top of a

12\,\text{m}

-high cliff. Neglecting air resistance, what is the ball’s translational kinetic energy immediately before it reaches the ground? a)

1.5\times10^{1}\,\text{J}

5.9\times10^{1}\,\text{J}

2.9\times10^{1}\,\text{J}

1.2\times10^{2}\,\text{J}
