Kinematics problems: Displacement in Moon & Proportionality

[Tanha Kate]

Homework Statement

An astronaut on the moon throws a stone horizontally with a speed V0. If the acceleration due to gravity on the moon is 1⁄6 that of the Earth, by what factor will the horizontal distance traveled by the stone, d, change?

Answer Options:
2

2.44

1.20

36

6

Homework Equations

The Attempt at a Solution

[/B]
Rearranging kinematic equation to make displacement the subject

Hence, inverse proportionality suggests displacement will increase by a factor of 6 but this is not the answer

When you use any formula, you must understand why that formula applies to the situation you are dealing with and what each term in the formula represents.

In this case, are you dealing with motion in one direction?

Also, what about the height above the ground that the stone is thrown?
