An alien spaceship has a mass of m = 3.2 x 10° kg, and accord- ing to the crew on board the bow-to-stern length is lo = 680 m. The ship passes by a space station at relativistic speed, and the technicians on the space station measure the length of the ship to be l = 550 m. What is the kinetic energy of the space %3D ship at this moment? (Hint: you don't need to solve for the ship's speed v in this problem. You only need to work in terms of y.)
