A rescue pilot wishes to drop a package of emergency supplies so that it lands as close as possible to a target. If the plane travels with a velocity of 18 m/s and is flying 225 m above the target, how far away (horizontally) from the target must the rescue pilot drop the package?

x = 121.86 m

Explanation:

It is given that,

The vertical velocity of a plane,

It is flying above the target, h = 225 m

First we will find the time taken by the plane to reach the ground. It can be calculated using the second equation of motion as follow :

Here, u = 0 and a = g

Let x is the horizontal distance from the target. It can be calculated as follows :

So, the rescue pilot drop the package at a distance of 121.86 m from the target.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

your answer is c! hope this : )
