    Answer:

    A)   Wn = 90J

    B)   W1 = 100J

         W2 = 10J

    Explanation:

    A) The net work done on the box is calculated by using the following formula:

    W_n=(F_1-F_2)d     (1)

    F1 = 100N

    F2 = 10N

    d: distance on which the box is moved = 1m

    You replace the values of the parameters in the equation (1):

    W_n=(100N-10N)(1m)=90J

    The net work on the box is 90J

    B) The total work done by each force is:

    W_1=F_1d=(100N)(1m)=100J\\\\W_2=F_2d=(10N)(1m)=10J

    The first box does a work of 100J and the second force does a force of 10J
