Question

an airplane pilot flying at constant velocity and altitude drops a heavy crate. where will the plane be relative to the crate when the crate hits the ground? behind the crate. very far in front of the crate. directly over the crate. barely in front of the crate.

Explanation:

When the crate is dropped from the airplane flying at constant velocity and altitude, it has the same horizontal - velocity as the airplane due to inertia. In the absence of air - resistance in the horizontal direction, both the plane and the crate move with the same horizontal speed. So when the crate hits the ground, the plane will be directly over the crate.

Answer:

C. Directly over the crate.
