Answer: The object moved 2 metres away 
Step-by-step explanation:
Given that the 
Force applied F = 20 N
Work done W = 40 J
From the definition of workdone which state that: product of force and distance 
W.D = F × S
Where S = distance 
S = W.D/F
S = 40/20 = 2 metres 
The object moved 2 metres away.
