Part 1: A ball is thrown horizontally from the top of a building 28.6 m high. The ball strikes the ground at a point 80.3 m from the base of the building. The acceleration of gravity is 9.8 m/s^2. Find the time the ball is in motion. Answer in units of s. Part 2: Find the init...
math
Since we know that the ladder is like the hypotenuse of a right triangle, we use the Pythagorous theorem. Which is what the person above used. any Right (90 degree) triangle with height (a) and base (b) has a hypotenuse (c) where a^2 + b^2 = c^2
