suppose a stone is launched with a speed of 27 m/s at an angle of 45C. It lands on the top of a 13.0m tall building. If the stone was launched when it was 1.0 m above the ground, what horizontal path does it travel before it arrives on the top of the building? Take g=9.8m/s^2

For which pair of objects would adding the same a
