An object of mass m = 2.7 kg moves with initial speed vinitial = 2.2 m/s, then interacts with its environment, releasing 4.4 J of work. What is the speed of the object after the interaction is completed?

My ans:
I found KE initially and then subtracted 4.4J and with the new value i recalculated v...but the answer was wrong. So I am not sure what i am doing wrong
