Velocity question i can't figure it out

Velocity question...i can't figure it out :(

A person throws a baseball straight up from the ground. The baseball leaves the persons hand with an initial velocity of 10.0 m/s [up]. The acceleration of the ball is 9.81 m/s 2 [down]. Assume up as the positive direction.

a. what is the velocity of the baseball after 0.50 s?
b. what is the velocity of the baseball after 1.50 s?

THANK YOU SOOO MUCH IN ADVANCE!

How would you go about solving the problem?

What is it you are stuck on?

For instance I know how to figure it out, but I'm not getting the grade, nor am I taking your tests.

How do you think to go about it?

I seriously have no idea...
this whole velocity is driving me crazy..
can you explain?

well, you know the Kinematical equations.
v = u + at
s = ut + 0.5at^2
v^2 = u^2 + 2as
Use them

let's start by asking you this : what formula's for velocity do you know ?
