A plane weighing 253kN lands on an aircraft carrier. The plane
is moving horizontally at 6.73m/s when a tail hook grabs hold of
the arresting cables. The cables bring the plane to a stop in a
distance of 84.0m.
1) How much work ( in MJ) is done on the plane by the
arresting cables?
2) what is the force (in kN) (assumed constant) exerted
on the plane by the cables? Enter a negative value if the force
exerted on the plane is opposite to its direction of motion. Enter
a positive value if the force exerted on the plane is in the
direction of motion.
