- Once released, how much time will elapse before the supply
package reaches the level of the island?
(Hint: Use the distance equation in the
y-direction.)
time = ____________
- Will the descent time of the supply package change if the
airplane's speed changes?
(a) Yes (b) No
- At what (horizontal) distance in front of the island should
the package be released in order to hit the island?
dx = ______________
- What is the package's horizontal speed when it reaches the
level of the island?
vx = _____________
- What is the package's vertical speed when it reaches the level
of the island?
vy = ____________
- What will be the package's flight angle with respect to the
level of the island as it descends?
q = ______________
Suppose the victims on the island can retrieve supply
packages that land within 30 meters of the island. The length of
the island is 50 meters along the direction you are
approaching.
- How far in front of the island would the airplane have to
release the supply package for it to land 30 meters in
front of the island?
dx (front) = _____________
- How far in front of the island would the airplane have to
release the supply package for it to land 30 meters in back
of the island?
dx (back) = _____________
- Time1 will be the time on your watch when you
release the package and it lands 30 meters in front of the
island. Time2 will be the time on your watch when you
release the package and it lands 30 meters in back of the
island. Calculate the amount of time you have to successfully drop
the package, namely, time1- time2.
time1- time2 = ________________
- What could be done to decrease the package's speed when it
reaches the ground?
