Q. A fireman 46.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 34.0° above the horizontal. If the speed of the stream as it leaves the hose is 40.0 m/s, at what height will the stream of water strike the building?

Q. A 1000-N crate is being pushed across a level floor at a constant speed by a force of 280 N at an angle of 20.0° below the horizontal.

(a) What is the coefficient of kinetic friction between the crate and the floor?

(b) If the 280 N force is instead pulling the block at an angle of 20.0° above the horizontal, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part(a). m/s2
