Physics: What is the value final velocity that was calculated

Please what is the value final velocity that was calculated

I think it's 30ms-¹ because there is no change in magnitude but direction.

<p>A physics student standing on the edge of a cliff throws a stone vertically downward with an initial speed of 10.0 m/s. The instant before the stone hits the ground below, it is traveling at a speed of 30.0 m/s. If the physics student were to throw the rock horizontally outward from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground?</p><p>Ignore air resistance and take the same launch and ground levels in both cases.</p>
