Problem Statement | Helicopters can be used to fight forest fires. One task they perform is to drop fire suppressant flu- ids on targeted hot spots. Consider a firefighting helicopter traveling horizontal with a constant speed V;. It flies at an alti- tude h above the ground. You've been tasked by the crew to calculate the horizontal distance d away from the fire, from which you must release the fluids to hit the fire. Assume air resistance is negligible. (a) Draw a physical representation for this situation. Be sure to include representations of your coordinate system, the initial and final velocity, displacement, and acceleration of the dropped fluid. (b) Find an equation for d in terms of the distance d in terms Vi, h, and g, the acceleration of gravity. This equation should have no numbers except for a 2 from one of the equations used to construct it. (c) Use Dimensional Analysis sensemaking to determine if your expression in part (b) is plausible. (d) If Vi = 44 m/s and h = 100 m, what must d be equal to hit the target
