5. At a track and field meet, the best long jump is measured as 8.10 m. The jumper took off at an angle of 31° to the horizontal. What was the initial speed of the jumper?7. A firefighter located a distance of 17.0 m from a burning building, directs a stream of water at an angle θ = 17.0° above the horizontal. At what height does the water strikes the building if the initial speed of the stream is 41.0 m/s?
