Question: A pistol that fires a signal flare gives it an initial velocity (muzzle velocity) of 125 m/s at an angle of 55.0 above the horizontal.

A pistol that fires a signal flare gives it an initial velocity (muzzle velocity) of 125 m/s at an angle of 55.0° above the horizontal. You can ignore air resistance. Find the flare's maximum height and the distance from its firing point to its landing point if it is fired
(a) On the level salt flats of U tab, and
(b) Over the flat Sea of Tranquility on the Moon, where g = 1.67 m/s2•
