7. Borg ships are cubical. A Borg ship is approaching earth. According to an observer
on earth, the Borg ship is 1000 m high, 1000 m wide, and has a depth of 200 m. Earth
launches a photon torpedo to destroy the Borg ship. The torpedo is launched from
earth with a velocity of 0.99. The torpedo was set on earth to go off in 2 hr.
