Since we are not given with the angle of inclination of the side of the hill, it is better if it is assume here that the hill is vertically straight. Given the initial speed, the distance can be calculate through the equation,

2gd = Vf² - Vo²

Substituting the known values and keeping in mind that Vf should be 0 at the topmost of the hill,

2 (-9.8 m/s²) (d) = 0 - (8 m/s) ²

The value of d from the equation above is 3.265 m.
