A small airplane flying horizontally with a speed of 147 mi/hr at an altitude of 390 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 4.5 ft/sec. If the drop is designed so that the package is to reach the ground 59 seconds after release at A, determine the horizontal lead L so that the package hits the target.

During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed v0 = 45 m/s at an angle θ = 41° above horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Air resistance may be ignored throughout this problem. Express the magnitude of the balls initial horizontal velocity vox in terms of vo and theta Find the ball's maximum vertical height Hmax in meters above the ground Express the magnitude of the balls initial vertical velocity voy in terms of Vo and theta

A grasshopper wants to jump over a thin vertical wall with the minimal possible jumping speed.The wall is h = 30 cm high and it is at distance d = 40 cm from the grasshopper. What should be the initial speed of the grasshopper? The gravitational acceleration is g = 9.8 m/s2 .Hint: The trajectory is not symmetrical to the wall. Express the starting speed v0 of the grasshopper in terms of the initial angle of elevation α, and then find the maximum of the v0(α) function

A ball is thrown vertically upward with an initial speed of 89 ft/sec from the base A of a cliff with H = 56 ft. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the magnitude of the impact velocity vB. Neglect air resistance and the small horizontal motion of the ball.
A rock is thrown at a window that is located 18.0 m above the ground. The rock is thrown at an angle of 40.0° above horizontal. The rock is thrown from a height of 2.00 m above the ground with a speed of 30.0 m/s and experiences no appreciable air resistance. If the rock strikes the window on its upward trajectory, from what horizontal distance from the window was it released? A) 71.6 m B) 53.2 m C) 29.8 m D) 48.7 m E) 27.3 m
A criminal is escaping across a rooftop and runs off the roof horizontally at a speed of 5 m/s, hoping to land on the roof of an adjacent building. Air resistance is negligible. The horizontal distance between the two buildings is D, and the roof of the adjacent building is 3.0 m below the jumping-off point. Find the maximum value for D.
Suppose that you're flying an airplane to deliver a package of food and supplies to people on the ground. They have prepared a target area where it is safe to land the package (which is padded so it can withstand the impact without damage). You are flying parallel to the ground at height h = 210 m and constant speed v = 99 m/s. How far will the package travel horizontally between the moment you release it from the plane and when it hits the ground? Assume you can ignore air resistance, and use g = 9.8 m/s2 in the downward direction.
A rescue plane flying horizontally at 72.6 m/s spots a survivor in the ocean 182 m directly below and releases an emergency kit with a parachute. Because of the shape of the parachute, it experiences insignificant horizontal air resistance. If the kit descends with a constant vertical acceleration of 5.82 m/s^2, how far away from the survivor will it hit the waves?
