Need help with velocity problems! PLease

Homework Statement

Work is also measured in Joules. If a 2.59 kg object moves a distance of 56.9 cm as a result of 38N of foce. How fast is the object moving.

Homework Equations

?

The Attempt at a Solution

I started by trying to find the velocity using the square root of 2K(kinetic Energy) divided by the mass.

what did you get for KE in terms of the values provided?

idk i need help with this stuff in general

The question is a bit fuzzy IMO, but it starts with a statement about work.

Work is defined as force x distance.

If we can assume that all of that work went into propelling the object and none into say potential energy like moving it up a ramp:

the kinetic energy of the mass should be equal to that same quantity.
