The Joker steals Wonder Woman's invisible jet that is carrying a crate of kryptonite. The jet is flying horizontally above the ground with a speed of 285 m/s when the crate falls from the cargo hold. If the crate covers a horizontal distance of 4,898 m before hitting the ground? How high is the jet off of the ground in meters? (Assume there are no effects from friction or air resistance and this is happening on Earth.)
