Question: A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 7.90 m/s at an angle of 23.0° below the horizontal. It strikes the ground 5.00 s later.

(b) Find the height from which the ball was thrown. Your response differs from the correct answer by more than 10%. Double check your calculations.
(c) How long does it take the ball to reach a point 10.0 m below the level of launching?
