A skier leaves the ramp of a ski jump with a velocity of v = 10.0 m/s at = 15.0 above the horizontal as shown in Figure P4.49 (page 94). The slope where she will land is inclined downward at = 50.0, and air resistance is negligible.

(c) Explain how you think the results might be affected if air resistance were included. Figure P4.49
A firefighter, a distance d from a burning building, directs a stream of water from a fire hose at angle i above the horizontal as shown in Figure P4.11. If the initial speed of the stream is vi, at what height h does the water strike the building? Figure P4.11
For a fixed initial speed, the range of a projectile is determined by the angle at which it is fired. For all but the maximum, there are two angles that give the same range. Considering factors that might affect the ability of an archer to hit a target, such as wind, explain why the smaller angle (closer to the horizontal) is preferable. When would it be necessary for the archer to use the larger angle? Why does the punter in a football game use the higher trajectory?
