Hypothetically, you are standing on the balcony of an apartment on the 10th level of a building and you throw a ball at some angle,è , above the horizontal away from the building. the ball lands on the ground 10m from the building, 3.2s after it was thrown. the height from which the ball is thrown was approximately 30m. find the angle è and the initial velocity of the ball.
