1. Suppose an airplane flew east along the equator from the Prime Meridian to the International Dateline; that is, exactly half way around the world. What is its final displacement? Is it the distance covered by its route of flight (12,450 miles) or the distance measured straight through the center of the earth (7,920 miles)? Suppose the trip took exactly one day. What would be the displacement as observed from the Sun?

2. Suppose the airplane flew at a steady 450 miles per hour, with respect to the surface of the Earth. Discuss, in qualitative (non-mathematical) terms, what its velocity would be with respect to other frames of reference: the center of the Earth, the Moon, the Sun, and the center of the Galaxy.

3. Comment on how the various safety features in new cars work to minimize injury. (Don't limit your discussion to seat belts.) Beginning with the notion that injuries are caused by forces (duh!), discuss the origins of forces in terms of velocity, distance, time, and acceleration. Shamelessly flaunt your detailed knowledge of the material covered in Modules 1 and 2 by using equations and numerical examples as appropriate.
