Problem 6 On a lake, a 1700-lbm jet boat pumps 32.0 gal/s of water While traveling at 35 mph. The water exits the rear of the boat with a velocity of 75 mph and provides forward thrust. The drag force on the boat is 110 lbf. What is the rate of change in linear momentum (lbm ft/sz) of the boat? After one second, What is the new velocity (mph) of the boat? Assume that the mass of 1 gallon of water is 3.78 kg
