A jet boat pumps high-velocity water horizontally out the rear to provide forward thrust. A 1500-lb jet boat pumps 25.0 gal/s of water while traveling at 30.00 mph. The water exits the rear of the boat with a velocity of 70 mph. The drag force on the boat is 100 lb. At what rate does the momentum accumulate (lb*ft/s^2) within the system (i.e., the boat)? What is the boat’s acceleration (ft/s^2)? After one second, what is the new velocity (mph) of the boat? (Note: The boat is travelling through stagnant water.)
