From the window of a building, a ball is tossed from a height y0 above ground with an intial velocity of 8.5 m/s and angle of 19.0 degrees, below the horizontal. It strikes the ground 6.00 seconds later.
(a) If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction, what are the intial coordinates ot the ball?
xi=
yi=
(b) with the positive x-direction chosen to be out the window, find the x- and y- components of the intial velocity.
Vi x = ____ m/s
Vi y = ____ m/s
(c) Find the equations for the x- and y- components of the position as functions of time.
x= _____m
y=_____m
(d) how far horizontallt from the base of the building does the ball strike the ground?
=_____m
(e) find the height from which the ball was thrown.
=_____m
(f) how long does it take the ball to reach a point 10.0m below the level of launching?
=_____s
