Use the work-energy theorem to find its maximum height

Reference no: EM13248230

You throw a 20-N rock vertically into the air from ground level. You observe that when it is a height 15.4m above the ground, it is traveling at a speed of 25.3m/s upward.

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

- Use the work-energy theorem to find its maximum height.
