1. A jet is flying with an air speed of 500 m/s. A parcel is dropped out of the plane. Assume that it takes 40 seconds for the parcel to hit the ground.. Assume no air resistance.
a. How high is the jet?
b. How far forward horizontally from the spot where it leaves the jet, does the parcel move during those 40 seconds?
c. Where is the parcel relative to the jet?
