centripetal acceleration=gravitational acceleration
v^2/r=3/5 g
solve for V. You need to know the radius of Mars.
An astronaut on the surface of Mars fires a cannon to launch an experiment package, which leaves the barrel moving horizontally. Assume that the free-fall acceleration on Mars is three eighths that on the Earth.(a) What must be the muzzle speed of the package so that it travels completely around Mars and returns to its original location?
