Explanation:
The mechanical energy is the sum of the kinetic energy and the potential energy of an object. The equation for the ball would be:
\[ME = KE + PE\] \[ME = \frac{1}{2}mv^2 + mgh\] \[ME = \frac{1}{2} \cdot (5 \text{ kg}) \cdot (10 \text{ m/s})^2 + (5 \text{ kg}) \cdot (9.8 \text{ m/s}^2) \cdot (15 \text{ m})\] \[ME = 985 \text{ J}\]All Flashcard Sets for the CSET Multiple Subjects Test are now available as downloadable PDFs
