Answer:
Explanation:
The work done on the object at rest is all converted into kinetic energy, so we can write
Or, re-arranging for v,
where
v is the final speed of the object
W is the work done
m is the object's mass
If the work done on the object is doubled, we have W' = 2W. Substituting into the previous formula, we can find the new final speed of the object:
So, the new speed of the object is .
