Question

4. A plane traveling at 200 m/s drops supplies from 1500 m above the ground. If it reaches
the ground after falling for 17.5 seconds, what is its horizontal displacement?

Answer 1

Answer:

3500 m

Explanation:

To find the horizontal displacement of the box of supplies, we just need to analyze its horizontal motion.

The horizontal motion of the box is a uniform motion with constant velocity, since there are no forces acting along this direction. Therefore, the horizontal displacement is given by

$d=v_x t$

where

$v_x$ is the horizontal velocity

t is the time

The horizontal velocity of the supplies is the same as the plane, therefore

$v_x = 200 m/s$

So, since the time of flight is

t = 17.5 s

The horizontal displacement is

$d=(200)(17.5)=3500 m$
