## Homework Statement

Inside a starship at rest on earth, a ball rolls off the top of a horizontal table and lands at a distance D from the foot of the table. This starship lands now at a planet called Planet X. The commander Captain Cudos rolls the same ball off the same table with the same initial speed as on Earth and finds that it lands a distance of 2.76D from the foot of the table. What is the acceleration due to gravity on Planet X?

## Homework Equations

x=(V0cosa0)t

y=(V0sina0)t - 1/2gt^2

Vx=V0cosa0

Vy=V0sina0-gt

## The Attempt at a Solution

I made up the initial speed since it was not given and assumed a time. and used y=(V0sina0)t - 1/2gt^2...came out completely wrong :(
