A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 9.10 m/s at an angle of 19.0° below the horizontal. It strikes the ground 4.00s later.
Find the height from which the ball wasthrown.
How long does it take the ball to reach a point 10.0 m below thelevel of launching?
