Can i get help with these problems

5. (II) Calculate the force exerted on a rocket when the propel-
ling gases are being expelled at a rate of 1300 kg/s with a
speed of 4.5 x 10 m/s.
6. (II) A 7700-kg boxcar traveling 14 m/s strikes a second car
at rest. The two stick together and move off with a speed of
5.0 m/s. What is the mass of the second car?
