A tennis ball is thrown from ground level with an initial velocity directed 30° above the horizontal. If it takes the ball 1 second to reach the top of its trajectory, what is the magnitude of the initial velocity?

2. Relevant equations

3. The attempt at a solution

I am new to physics and the only attempt I made towards this problem is a visual drawing of the problem. I do not understand what they mean by "what is the magnitude of the initial velocity?" Can someone please explain what I have to find here
