An unpowered projectile is fired vertically upwards from the surface of the Moon. To what height above the surface will the projectile rise if it leaves the surface at $1500\frac{m}{s}?($The mass of the Moon is $7\mathrm{.}35{10}^{22}Kg$ and the radius of the Moon is $1\mathrm{.}74{10}^{6}m$ and $E_p=-G\frac{m_1{m}_z}{r}.)$

A$.8\mathrm{.}5{10}^{7}m$

B$.1\mathrm{.}2{10}^{7}m$

C$.1\mathrm{.}3{10}^{6}m$

D$.6\mathrm{.}1{10}^{6}m$
