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
