From the window of a building, a ball is tossed from a height y, above the ground with an initial velocity of 7.80 mts and angle of 25.0" below the horizontal, It strikes the ground 5.60 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. Yo Assume
St units. Do not substitute numerical values; use variables only)
X-
Y-
(b) With the positive x direction chosen to be out the window, find the x and y-components of the initial velocity
m's

(d) How far horizontally from the base of the build does the ball strike the ground?
() Find the height from which the ball was thrown
m
