1) A rock is thrown horizontally from the top of a building with an initial speed of v = 11.1 m/s. If it lands d = 43.5 meters from the bottom, how high is the building?
2) Salmon often jump upstream through waterfalls to reach their breeding grounds. One salmon came across a waterfall 1.11 m in height, which she jumped in 1.97 s at an angle of 36.0° to continue upstream. What was the initial speed of her jump?
