    9,000 N.

    Explanation:

    Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.

    Mathematically,

    W = F * d

    = 180,000/2

    = 90,000 N.

    Weight of the 10 cars = 90,000 N.

    Weight of a car = 90000/10

    = 9,000N.
