A rocket is fired vertically upward. At the instant it reaches some altitude with a speed of 100 m/s. It explodes into three fragments having equal mass. One fragment moves upward with a speed of 150 m/s following the explosion. The second fragment has a speed of 150 m/s and is moving east right after the explosion. What is the velocity of the third fragment immediately after the explosion?
