How can the final speed of books sliding on a ramp be calculated?

[huh]

A box of textbooks of mass 24.4 rests on a loading ramp that makes an angle a with the horizontal. The coefficient of kinetic friction is 0.230 and the coefficient of static friction is 0.360 . I figured out that the angle is 19.8 and acceleration is 1.2m/s^2. I would like to know how to figure out the speed after it's slid 5.20 m.

For constant acceleration, velocity at some distance is given by

v² = v_o² + 2 a x, where 'a' is acceleration, x is the distance traveled, and v_o is the initial velocity.
