On earth, a ball is launched with speed v₀ at an angle 45° above the horizontal. by the time it lands, it travels a horizontal distance r (the "range" of the ball). what is the range of the ball if the ball is launched on the moon, where the magnitude of the acceleration due to gravity is 1/6th as large as on the earth?

A. √6R
B. R/√6
C. R/6
D. 6R
E. R
F. I DON'T KNOW YET
