Problem 12-60: Engineering Mechanics- Dynamics (Hibbeler 14th Edition)

Engineering Mechanics Dynamics · R.C. Hibbeler · Chapter 12

Question

A package is dropped from an elevator at a height of 100 ft above the ground. The elevator maintains a constant upward speed of 4 ft/s. The package is released with the same upward speed as the elevator. Assume gravitational acceleration is 32 ft/s². 1. Determine the height of the elevator from the ground at the instant the package hits the ground. 2. Draw the velocity-time curve for the package during its motion.
