    Solution for this problem is we will be using the following formula:

    Work done by applied force) = Force (applied) x s x cos θ

    Where:

    Force applied = 12 N

    s = 13 m long

    Angle = 17

    So plugging in the values:

    =>W (a) = 12 x 13 x cos 17

    = 12 x 12.43196182

    = 149.1835 J
