- An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth. What angle (in degrees) above the horizontal must he spit?A fireman d = 52.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of ?i = 21.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building?A fireman d = 38.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of ?i = 22.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building?
- Athena is planning a flight from Toronto to Montreal, which lies due east of Toronto. Her aircraft flies at a speed of 800.0 km/h in still air. A wind of 50.0 km/h is blowing from [W 30.0° N]. In what direction must she aim the airplane to fly directly to Montreal ?In Canadian football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ftft above the ground, and the ball is kicked from ground level, 36.0 ftft horizontally from the bar in (Figure 1). Football regulations are stated in English units, but convert to SI units for this problem. If the ball is kicked at 39.0 ∘∘ above the horizontal, what must its initial speed be if it is just to clear the bar? Express your answer in m/sm/sAt what angle should you throw the ball?
- Question 20 of 20 < A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?

(b) How should her angle of aim change depending on the distance to the target? (c) Suppose the archer's arrow is 1.2m above the ground, the bull's eye is 43m away and at a height of 1.8m, and she can shoot the arrow at an initial speed of 28m/s. It is a calm day with no wind so we ignore air resistance. At what angle should she aim her arrow to hit the bull's eye? Not incomplete
