A plane weighing 220 kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 64.0 m/s (141 mi/h) when its tailhook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 84.0 m. (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?
