    1. The problem statement, all variables and given/known data

    A mechanic jacks up a car to an angle of 10◦
    with the horizontal in order to change the
    front tires. The car is 3.08 m long and has a
    mass of 1129 kg. Its center of mass is located
    1.54 m from the front end. The rear wheels
    are 0.4 m from the back end.
    Calculate the torque exerted by the car
    around the back wheels. The acceleration of
    gravity is 9.81 m/s2 .
    Answer in units of N · m.

    2. Relevant equations


    3. The attempt at a solution

    Basically, I don't know what the question is really asking... And how do i start?
