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
