You throw a 3.00 N rock vertically into the air from ground level. You observe that when it is 16.0 m above the ground, it is traveling at 23.0 m/s upward. Part A Use the work-energy theorem to find the rock's speed just as it left the ground. Express your answer with the appropriate units. v2 = Submit Request Answer Part B Use the work-energy theorem to find its maximum height. Express your answer with the appropriate units. hmax =
