Vertical velocity of a soccer ball

[ahrog]

Homework Statement

A force of 17.0 N is applied to a 0.34 kg soccer ball for 0.090s, causing it to move off at 28 degrees above the horizontal. Determine the vertical velocity of the soccer ball at the end of the 0.090 second time interval.

Homework Equations

y= v_yt + 1/2gt²
v_yf= v_y + gt
vf= vi + at

The Attempt at a Solution

I don't really understand how to do this. How should I go about doing this? I'm thinking that maybe I have to find the acceleration of the ball, then find the velocity, but I'm not really sure how I should go about doing that.

You're missing change in momentum that comes from the impulse of the kick delivered.

So what do you suggest I do?

Maybe look at this link:

That doesn't help me much...

Really?

The ball is at rest. Then it has a velocity. That looks like a Δv to me

There is a force and there is the time it's applied that looks like a Δt.

I suggest you reread this link.
