Question
physics
Please help! The answers to Parts A-C are solved. Therefore Part D is only needed.
9. A package is dropped from an airplane that is thying 323 metens above the ground, and moving so the i of with a constant horizormal velocity of 75 8 m's The initial velocity of the package in the airplane's firame of eeference is zero. Ignore the effeets of air resistanoe. a. (5 points) Whot is the initial velocity of the package in the frame of reference of an obeerver at rest on h. Ar wlal poirt will the package hit he gousd, relative to the point on the ground directly undkr the c. What is the velcity of the package when it hits the ground in the frame of eference of the airplane d. What is the velocity of the package when it hits the ground in the franme of reference of an observer at he ground airplane when the pockage was droppod? Give your uns wer·x a magnitule and direction relative to the horizontal. rest on the grourd? Give your answer as a magnitude and direction relstive to the horizunal.
Explanation / Answer
Here ,
d)
let the final speed of package when it touches ground is v m/s
initial speed , u = 75.8 m/s
height , h =325 m
using third equation of motion
v^2 - u^2 = 2 * a * d
v^2 - 75.8^2 = 2 * 325 * 9.8
v = 110.1 m/s
the speed of package when it hit ground is 110.1 m/s
