Warm Up: The engine on a fighter airplane can exert a force of 105,840 N (24,000 pounds). The take-off mass of the plane is16,875 kg. (It weighs 37,500 pounds.) If you mounted this aircraft engine on your car, what acceleration would you get? (Please use metric units. The data in pounds are given for comparison. Use a reasonable estimate for the mass of your car. A kilogram mass weighs 2.2 pounds.)
