Need help with velocity problems!!!! PLease

1. The problem statement, all variables and given/known data
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.


2. Relevant equations
?


3. 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.
 
Re: Need help with velocity problems!!!! PLease

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

idk i need help with this stuff in general
 
Re: Need help with velocity problems!!!! PLease

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.
