Question

A plane is flying horizontally with speed
235 m/s at a height 6040 m above the ground,
when a package is dropped from the plane.
The acceleration of gravity is 9.8 m/s2 .
Neglecting air resistance, when the package
hits the ground, the plane will be
1. ahead of the package.
2. directly above the package.
3. behind the package.

What is the horizontal distance from the re-
lease point to the impact point?
Answer in units of m


A second package is thrown downward from
the plane with a vertical speed v1 = 51 m/s.
What is the magnitude of the total velocity
of the package at the moment it is thrown as
seen by an observer on the ground?
Answer in units of m/s


What horizontal distance is traveled by this
package?
Answer in units of m

Explanation / Answer

The package in Free-Fall will hit with the plane directly over it. The package is moving horizontally at the same speed as the plane, so although they separate vertically they don't separate horizontally (until package stops moving on the ground).
