    Answer: 10Nm or 10J

    Explanation:

    Given the following:

    Force (f) = 5

    Distance (d) = 2m

    Calculate the kinetic energy assuming no friction

    Work done = force * distance

    Work done = 5N * 2m = 10Nm

    Recall:

    Work done = ΔK. E (change in kinetic energy)

    Therefore, kinetic energy of the book after sliding = ΔK. E, which is equal to work done.

    Hence, K. E of book after sliding is 10Nm
