# Acceleration on Earth Vs Moon

The weight of any object on the Moon gets reduced to 1/6th 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:

A) 1 : 6
B) 31 : 36
C) 36 : 31
D) 6 : 1 Continue reading Acceleration on Earth Vs Moon

# $v^2-u^2 \neq 2as$

When a particle is thrown up vertically from the surface of the earth (radius R), we have v2-u2=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 $\displaystyle {{v}^{2}}-{{u}^{2}}=2(-g)h\frac{1}{\left( 1+\frac{h}{R} \right)}$.
