At a particular instant, a hot air balloon is 50.3 m above a horizontal field and descending at a rate of 3.5 m/s.

An airplane flies horizontally above the flat surface of a desert at an altitude of 5 km and a speed of 915 km/h. If the airplane is to drop a care package that issupposed to hit a target on the ground, where should the plane be with respect to the target when the package is released? (Enter the horizontal distance between theplane and the target.) If the target covers a circular area with a diameter of 45 m, what is the "window of opportunity" (or margin of error allowed) for the release time?
A bomber is flying horizontally over level terrain at a speedof 275 m/s relative to the ground and at an altitude of3.00 km. (a) The bombardier releases one bomb. How fardoes the bomb travel horizontally between its release and itsimpact on the ground? Ignore the effects of air resistance.(b) Firing from the people on the ground suddenly incapacitatesthe bombardier before he can call, “Bombs away!”Consequently, the pilot maintains the plane’s originalcourse, altitude, and speed through a storm of flak. Whereis the plane relative to the bomb’s point of impact when thebomb hits the ground? (c) The plane has a telescopic bombsightset so that the bomb hits the target seen in the sight atthe moment of release. At what angle from the vertical wasthe bombsight set?
A playground is on the flat roof of a city school, 6.00m above the street below. The vertical wall of the building is h=7.00m high, forming a 1-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of ɵ=53.0o above the horizontal at a point d=24.0 m from the base of the building wall. The ball takes 2.20s to reach a point vertically above the wall. Find the vertical distance by which the ball clears the wall. show the complete solution.
