An airplane is in level flight over Antarctica, where the magnetic field of the earth is mostly directed upward away from the ground. As viewed by a passenger facing toward the front of the plane, is the left or the right wingtip at higher potential? Does your answer depend on the direction the plane is flying?

A jet takes 5 3/4 h to fly 2,475 mi from New York City to Los Angeles. About how many hours will a jet flying at the same average rate take to fly 5,452 mi from Los Angeles to Tokyo?

Suppose that you are flying in a fighter jet and an enemy jet is headed straight at you from behind with acceleration vector parallel to your principal unit normal vector. Discuss how much danger you are in and what maneuver(s) you might want to make to avoid danger.

A metal rectangle is close to a long, straight, current-carrying wire, with two of its sides parallel to the wire. If the current in the long wire is decreasing, is the rectangle repelled by or attracted to the wire? Explain why this result is consistent with Lenz’s law.

An archer shoots an arrow from a height of $1.14 \mathrm{~m}$ above ground with an initial velocity of $47.5 \mathrm{~m} / \mathrm{s}$ and an initial angle of $35.2^{\circ}$ above the horizontal. At what time after the release of the arrow from the bow will the arrow be flying exactly horizontally?

Write an equation that relates the quantities. A plane flying horizontally at an altitude of 1 mi and a speed of 500mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station.

Draw a picture of the situation for any time t. A plane flying horizontally at an altitude of 1 mi and a speed of 500mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station.

Three radar sets, operating independently, are set to detect any aircraft flying through a certain area. Each set has a probability of .02 of failing to detect a plane in its area. If an aircraft enters the area, what is the probability that it is detected by all three radar sets?
