A ball is tossed from an upper-story window of a house. The ball is given an initial velocity of 7.70 m/s at an angle of 20.0o below the horizontal. It strikes the ground 3.00 second later.
a) Find how far horizontally from the base of the building does the ball strike the ground?
b) Calculate the height from which the ball was thrown.
c) Calculate how long does it take the ball to reach a point 10.0 meter below the level of launching?
