A ball tossed vertically upward from the ground next to a building passes the bottom of a window \(1.8 \mathrm{~s}\) after being tossed and passes the top of the window \(0.20 \mathrm{~s}\) later. The window is \(2.0 \mathrm{~m}\) high from top to bottom.

(a) What was the ball's initial velocity?

(b) How far is the bottom of the window from the launch position?

(c) How high does the ball rise above the launch position?
