Question

a plane is dropping provisions to a village. if they drop a crate of supplies and are moving sideways at a speed of 180 mph, where is the most unsafe place for the villagers to stand if they want to avoid getting hit?
a directly under the plane as it drops the supplies
b behind the plane as it drops the supplies
c inside of the plane as it drops the supplies
d ahead of the plane as it drops the supplies

Explanation:

When the plane drops the crate, due to the horizontal - motion inertia of the crate, it will continue to move horizontally at the same speed as the plane (180 mph) while falling. So the crate will land directly under the position of the plane at the moment of dropping.

Answer:

A. Directly under the plane as it drops the supplies
