A ball is tossed from an upper story window of a building. The ball is given an initial velocity of 8.00m/s at an angle of 20.0? Below the horizontal. It strikes the ground 3.00 s later.
[A] How far horizontally from the base of the building does the ball strike the ground?
[B] Find the height from which the ball was thrown.
[C] How long does it take the ball to reach a point 10.0 m below the level of launching?
