Hunter pushed a couch across the room. He did 800 J of work in 20 seconds. The couch weighed 500 N. How much power did he have?
A . 40 W
B . 1.6 w
C. 16,000 w
D . 800 w

Respuesta :

The answer is d Because if you take the 800+ the 20th I will give you 820 then plus the 500 then subtract another 20-10 divide 45 then you’ll end up with your original number 800
