From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 9.40 m/s and angle of 23.0° below the horizontal. It strikes the ground 6.00 s later.

Initial velocity components:

vx = 8.65 m/s

vy = -3.67 m/s

(c) Find the equations for the x- and y- components of the position as functions of time.

x = 8.65t

y = ?

(d) How far horizontally from the base of the building does the ball strike the ground?

51.9 m

(e) Find the height from which the ball was thrown.

(f) How long does it take the ball to reach a point 10.0 m below the level of launching?

I need help on (c), (e), and (f).
