A small airplane flying horizontally with a speed of 170 mi/hr at an altitude of 400 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 6.1 ft/sec. If the drop is designed so that the package is to reach the ground 46 seconds after release at A, determine the horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B. B Target- L 170 mi/hr 400'
