Vertical Component of this Picture?

[Imminent Fate]

A ball of mass 0.6 kg, initially at rest, is
kicked directly toward a fence from a point
20 m away, as shown below.
The velocity of the ball as it leaves the
kicker’s foot is 17 m/s at angle of 52◦
above
the horizontal. The top of the fence is 7 m
high. The ball hits nothing while in flight and
air resistance is negligible.
The acceleration due to gravity is 9.8 m/s

What is the vertical component of the velocity
when the ball reaches the plane of the fence?
Answer in units of m/s


I've tried -1.764

You should show your working (preferably with algebraic variables and constants rather than actual numbers), so then we can see how to help.
