A marksman standing on a motionless railroad car fires a gun into the air at an angle of 30.00 °from the horizontal. The bullet has a speed of  175 m/s (relative to the ground) and a mass of  0.019 kg. The man and car move to the left at a speed of 1.5 ×10−3 m/s after he shoots. What is the mass of the man and car? Round the answer to two significant figures.
