What is the total mechanical energy present at the height

Reference no: EM13643325

You throw a 29.7 rock vertically into the air from ground level. You observe that when it is a height 16.4 above the ground, it is traveling at a speed of 21.2 upward. What is the total mechanical energy present at the height given? What is its speed just as it left the ground? What is its maximum height?
