A projectile of mass m is fired from the surface of the earth at an angle A from the vertical. The initial speed Vo is equal to the square root (GMe/Re). How high does the projectile rise? Neglect air resistance and the earth's rotation. (Hint: It is probably easier to apply the conservation laws directly instead of using orbit equations.)

At the highest point, its kinetic energy must be equal to the potential energy.
ie, (1/2)mv^2 = mgh (considering 90 degree ...
