From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 8.10 m/s and angle of 18.0° below the horizontal. it strikes the ground 4.00 s 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 initial coordinates of the ball? (use the following as necessary: y0.) xi = yi = (b) with the positive x-direction chosen to be out the window, find the x- and y-components of the initial 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. (use the following as necessary: y0 and t. let the variable t be measured in seconds.) x = m y = m (d) how far horizontally 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 10.0 m below the level of launching? s
