- 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 P3.16. If the initial speed of the stream is vi, at what height h does the water strike the building? Figure P3.16A 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?A fireman d = 40.0 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? m A fireman on the ground sprays water from a fire hose onto a building. The water leaves the hose with velocity vector vi at an acute angle ?i above the horizontal and curves downwards just before it strikes the building at a height h above the ground. The building is a horizontal distance d from the fireman.
- the water in a river flows east at a speed of 1.00m/s relative to the shore. suppose your boat at a speed of 4.00m/s relative to the water. your goal is row directly from point A on the south shore to point B on the north shore of the river, without being carried upstream or downstream. In what direction do you need to aim your boat give your answer as angle west of north. If the river is 25.0 meters wide, how long will it take you to get across give your answer in secondsDaily Commissions. Ganyu used her charged attack to shoot an arrow hitting a hilichurl tower a certain distance away from her. Assuming there is no air resistance and the arrow hits the tower at the same height as the launch point, if the tower is 50.0 [m] away from Ganyu and the arrow has an initial velocity of 24.0 [m/s], at what angle did Ganyu launch the arrow?

Calvin is throwing water balloons at Hobbes: Calvin is throwing the water balloons with speed VO at an angle of 0 below the horizontal. On his first try, Calvin hits Hobbes with the water balloon! Hobbes is 3.02 m horizontally from the base of the building and it takes 1.04 s for the balloon to hit him. Coordinate system: positive x points to the right and positive y points up.
