A small airplane flying horizontally with a speed of 132 mi/hr at an altitude of 270 ft above a remote valley drops an emergency medical package at A. The package has a parachute which deploys at B and allows the package to descend vertically at the consta rate of 6.2 ft/sec. If the drop is designed so that the package is to reach the ground 29 seconds after release at A, determine the horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B. 132 mi/hr A

Question
A small airplane flying horizontally with a speed of 132 mi/hr at an altitude of 270 ft above a remote valley drops an emergency
medical package at A. The package has a parachute which deploys at B and allows the package to descend vertically at the constant
rate of 6.2 ft/sec. If the drop is designed so that the package is to reach the ground 29 seconds after release at A, determine the
horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B.
