A firefighter, a distance d from a burning building, directs a stream of water from a fire hose at angle e, above the horizontal as shown. If the initial speed of the stream is vi at what height h does the water strike the building?

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?

Danielle launches a ball off of a platform of height h with velocity vo at an angle 0 above the horizontal. A wall with a ball-sized hole a height H above the floor, with H > h, is a horizontal distance L = 24.0 m away from Danielle. The difference in height between H and h is one-twelfth of L, and the square of the magnitude of the velocity, v, is three-halves of the product gL. H 1 H – h = h 3 L Determine the two values of 0 that ensure the ball passes through the hole. Submit the larger angle as 0, and the smaller angle as 02.
