Define the work-energy theorem

Reference no: EM13511603

You throw a 20-N rock vertically into the air from ground level. You observe that when it is a height 14.6 m above the ground, it is traveling at a speed of 25.2 m/s upward.

Use the work-energy theorem to find its speed just as it left the ground.
