if you launch something on earth and it goes 10 feet on earth before landing, how far will it go on mercury?

Question

gravity on mercury is .38 the amount it is on earth

k thats pretty complicated but the last line helps a lot thnx

Answer 1

vx = hor. v, vy = vert. v
Distance = vx*time.
Time = time up + time down = 2*vy/g
Thus distance = 2*vy*vx/g, in other words it's inversely proportional to g for a given launch velocity and angle.
Answer = 10 ft/0.38
