small airplane flying horizontally with a speed of 168 mi /hr at an altitude of 395 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 6.6 ft/sec. If the drop is designed so that the package is to reach the ground 39 seconds after release at A, determine the horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B. Calculate the time t1 at which the parachute opens. Answer: t1 = ____ sec

Question
A small airplane flying horizontally with a speed of 168 mi /hr at an altitude of 395 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 6.6 ft/sec. If the drop is designed so that the package is to reach the ground 39 seconds after release at A, determine the horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B.
Calculate the time t1 at which the parachute opens.
