16. A ball traveling with an initial momentum of 4 kg-m/s bounces off a wall and comes back in the opposite direction with a momentum of -2 kg-m/s.
       What is the change in momentum of the ball?







17. A 5000 kg truck traveling with a velocity of 10 m/s due north collides head-on with a 1500 kg car traveling with a velocity of 20 m/s due south. The two vehicles stick together after the collision.
What is the total momentum of the two vehicles prior to the collision?








18. The load-bearing piston in a certain hydraulic system has an area 30 times as large as the input piston. If the larger piston supports a load of 9000 N. how large a force must be applied to the input piston?







19. With the temperature held constant, the pressure of a gas in a cylinder with a movable piston is increased from 40 kPa to 80 kPa. The initial volume of the gas in the cylinder is 0.12 m^3. What is the final volume of the gas after the pressure is increased?
