A plane drops a supply crate from an altitude of 8500 m, trying to hit a landing target. The plane's horizontal speed is 483 km/hr. Assume air resistance is negligible.
How long will it take for the crate to fall from the plane to the ground?

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

How is the gravitational force related to the distance between two objects?
