A particle of mass 'm' is projected with a velocity $$\upsilon $$ = kV_e = (k < 1) from the surface of the earth. (V_e = escape velocity)

The maximum height above the surface reached by the particle is :

$${{R{k^2}} \over {1 - {k^2}}}$$

$$R{\left( {{k \over {1 - {k^2}}}} \right)^2}$$

$$R{\left( {{k \over {1 + {k^2}}}} \right)^2}$$

$${{{R^2}k} \over {1 + k}}$$
