    Answer:

    50 W

    Explanation:

    Given :

    • Force applied = 100 N
    • Distance covered = 5 metres
    • Time = 10 seconds

    To find :

    Power

    Solution :

    For calculating power, we first need to know about the work done.

     \bf \boxed{Work = Force \times displacement}

    Now, substituting values in the above formula;

    Work = 100 × 5

    = 500 Nm or 500 J

    We know that,

    \bf \boxed{Power=\dfrac{Work\:done}{Time\: taken}}

    Substituting values in above formula;

    Power = 500/ 10

    = 50 Nm/s or 50 W

    Hence, power = 50 W .
