Question

A care package is released from an airplane in level flight 45 m above the ground. The package lands 200 m (horizontally) from the point where is was released. (a.) What was the speed of the plane? (b.) What speed of impact with the ground should the care package be designed to withstand?

An airplane is traveling at 80 m/s at a height of 200 m, and drops a relief package to refugees below, but the parachute attached to the package fails to open. The package was dropped with zero initial velocity relative to the plane. (a) How long does it take for the package to hit the ground? (b) How far does the package travel horizontally before it lands? (c) What is the velocity of the package when it lands? Report a vector quantity (either components, or magnitude and direction). (d) What is the speed of the package?

A plane drops a package of emergency rations to a stranded party of explorers. The plane is traveling horizontally at 40.0 m/s at 100 m above the ground. a) Find the time of flight in air for the package before it hits the ground. b) where the package strikes the ground relative to the spot it was dropped (the distance L). c) the velocity of the package just before it hits the ground.

00:01 Hello, here care package was released from an airplane when it was flying in the height of 45 meters above the ground.
00:15 And it landed at the distance of 200 meters from the point of the release.
00:22 First in question, you have to find speed of the plane.
00:27 Let's make the sketch.
00:30 Here, the vertical component of the speed was zero...
