(a) How much work is done on the plane by the arresting cables?

(b) What is the force (assumed constant) exerted on the plane by the cables?

(a)

For this problem I used

Work = K where K =1/2(mv^2)

k=1/2((220)(64^2))

k = 450.56

(b) work = F*x

450.56 = F*84

F=5.36

However, I got it wrong. What am I doing wrong?
