Find how much mass must be expelled

Reference no: EM13515098

A rocket of total mass 3160 kg is traveling in outer space with a velocity of 120 m/s. To alter its course by 38.5 degrees, its rockets can be fired briefly in a direction perpendicular to its original motion.

If the rocket gases are expelled at a speed of 1650 m/s, how much mass must be expelled?
