Any help appreciated on parts C, D, E, F :) 

 

Thank you!!!

From the window of a building, a ball is tossed from a height y, above the ground with an initial velocity of 9.10 m/s and angle of 25.0° 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 y-direction, what are the initial coordinates of the ball? (Use the following as necessary: y: Assume SI units. Do not substitute numerical values;
use variables only.)
