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. 09 ce 1000 m Earth 200m a) With what velocity is the Borg ship approaching earth? b) What is the speed of the torpedo as measured by an observer on the Borg ship? ) According to an observer on the Borg ship, how long will it take the torpedo to explode?
