## Homework Statement

An astronaut on a strange planet finds that he can jump a

__maximum__horizontal distance of 30m if his initial speed is 9m/s. What is the acceleration of gravity on the planet?

## Homework Equations

Vf^2=Vi^2+2a(Xf-Xi)

## The Attempt at a Solution

I used the formula mentioned above, plugged in number

Vf=0m/s

Vi=9m/s

X=Xf-Xi=30m

and get a=-1.35m/s^2

I'm not sure if it is correct, could someone double check and tell me if I did anything wrong? Thanks
