Question-6 : An Asteroid Tragedy!!

While on your space mission, you encounter a swarm of asteroids and crash land on an exoplanet. Luckily your shuttle has an emergency escape capsule and some fuel left. In order to plan your escape you need to know the escape velocity of the planet you are stranded on. You have a weighing machine, a shovel and a filled water container of 1 litre. You know your weight to be "W" newtons on earth and exoplanet has a g' m/s^2 acceleration due to gravity. Assume that the density of the exoplanet is constant. Using the above data and the items in hand, calculate the escape velocity.
