QUESTION:

Problem 14E

Section 4.3 Projectile Motion

A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 100 m above the glacier at a speed of 150 m/s. How far short of the target should it drop the package?

ANSWER:

Step 1 of 2

We have to find how short of the target should a supply plane drop the package.

The time of flight for the package of food in free fall in the negative direction can be found using the kinematic equation.

                                               

Where,

 m

 m

- component of initial velocity = 0 m/s

time of flight in s

 

Thus,

                                                     

                                                   

                                                    = 4.50 s
