The weight of any object on the Moon gets reduced to 1/6^{th} of its value on the Earth. X can apply a maximum force of 300 N. The ratio of the maximum acceleration on the Earth to that on the Moon of a 6 kg object that X can throw is approximately:

When a particle is thrown up vertically from the surface of the earth (radius R), we have v^{2}-u^{2}=2(-g)h (h << R) if the effects due to the atmosphere of the earth are neglected (symbols mean the usual things). However, if h << R condition is not applicable, prove that . Continue reading →
