**Finding Final Speed Using Work**

A person pushes with a horizonal 25N force over a distance of 1.2m on a 4.5kg crate, intially at rest on a frictionless surface. What is the final speed of the crate?

heres my data list..

F=25N

delta d=1.2m

m=4.5kg

v1=0

v2=?

theta=0 degrees

i used the W=fxdeltadxcos(theta) formula to find out the work done was 30J.. but once i have work i dont no what to find next to find the final speed..
