    Answer:

    50 W

    Explanation:

    Power can be found using the following formula.

    p=w/t

    where w is work and t is time.

    400 Joules of work is done on the object in 8 seconds. Therefore,

    w= 400 J

    t= 8 s

    Substitute these values into the formula.

    p=400 J/ 8 s

    Divide 400 by 8

    p=50 J/s

    Add appropriate units. In this case, power uses Watts, or W. (1 Joule per second, or J/s is equal to 1 Watt, or W)

    p= 50 W

    The object experiences 50 Watts of power
