From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 8.20 m/s and angle of 23.0° below the horizontal. It strikes the ground 6.00 s later.
(a) If the base of the building is taken to be the origin of the coordinates, with upward the positive ydirection, what are the initial coordinates of the ball? (Use the following as necessary: y0.)
(b) With the positive xdirection chosen to be out the window, find the x and ycomponents of the initial velocity.
(c) Find the equations for the x and y components of the position as functions of time. (Use the following as necessary: y0 and t. Let the variable t be measured in seconds.)
(d) How far horizontally from the base of the building does the ball strike the ground?
