A man can jump on the moon six times as high as on the earth. Why?

Answer:

                Maximum height attained on earth, \[H=\frac{{{u}^{2}}{{\sin }^{2}}\theta }{2g}\] Acceleration due to gravity on moon, \[g'=g/6\] \[\therefore \] Maximum height attained on moon, \[H'=\frac{{{u}^{2}}{{\sin }^{2}}\theta }{2g'}=\frac{6{{u}^{2}}{{\sin }^{2}}\theta }{2g}=6H\] So one can jump on moon six times as high as on earth.
