Calculating Object Speed: Work, Mass, and Velocity Methods Explained

[EES]

Is there any way to calculate the speed an object given work done and object's mass. I kno W=mad or .5mv^2.

work done on an object = change in kinetic energy

work = 0.5m(vfinal)^2 - 0.5m(viniitial)^2

if vinitial = 0

work = 0.5m(vfinal)^2

just solve for vfinal in this equation.
