1. The problem statement, all variables and given/known data A bolt comes loose from the bottom of an elevator when it is at a height of 15 m above the bottom of the elevator shaft. If the elevator is originally moving upward at a speed of 7.5 m/sec, assuming that the elevator continues to ascend at a constant speed, how high above the ground will the elevator be when the bolt reaches the ground. 2. Relevant equations Seen in attempt. 3. The attempt at a solution I am graded X/10 based on whether my answer is correct and if I show all work possible for this problem.
