A starship is built to plans that state it is to be constructed 100. meters long. It is launched and as it coasts by the Earth, it is seen to be shortened to 5.48 meters long

(a) How fast is it moving?
(b) The ship's crew measure the length of the ship to be how long?


(a) 99.85% the speed of light
(b) 100. meters

An object consists of a rod (of length 3.0 m and negligible moment of inertia) to which four small 2.0-kg masses are attached, one at each end and one at each point on the rod 1.0 m from each end. (The masses are one meter apart.) The moment of inertia of this object about an axis perpendicular to the rod and through one of the end masses:

a. is 28 kg•m2. b. is 12 kg•m2. c. is 4 kg•m2. d. cannot be uniquely determined until it is stated which inner mass the axis goes through.
