An object is projected vertically upward...

An object is projected vertically upward from the surface of the earth of mass `M` with a velocity such that the maximum height reached is eight times the radius `R` of the earth. Calculate:
(i) the initial speed of projection
(ii) the speed at half the maximum height.
