A forest fire is easiest to attack when it’s just getting started. In remote locations, this often means using airplanes to rapidly deliver large quantities of water and fire suppressant to the blaze.                                  The “Superscooper” is an amphibious aircraft that can pick up a 6000 kg load of water by skimming over the surface of a river or lake and scooping water directly into its storage tanks. As it approaches the water’s surface at a speed of 35 m/s, an empty Superscooper has a mass of 13,000 kg.a. It takes the plane 12 s to pick up a full load of water. If we ignore the force on the plane due to the thrust of its propellers, what is its speed immediately after picking up the water?b. What is the impulse delivered to the plane by the water?c. What is the average force of the water on the plane?d. The plane then flies over the fire zone at 40 m/s. It releases water by opening doors in the belly of the plane, allowing the water to fall straight down with respect to the plane. What is the plane’s speed after dropping the water if it takes 5.0 s to do so?
