PLEASE HELP ME

You are moving 6 books, each weighing 11 N, to a shelf 0. 8 m higher. Do you do more work by moving all 6 books at once, or by moving one book at a time?

Respuesta :

Answer:

word done = fore * distance moved by the force, so 11n * 0.8=8.8j then 8.8 * 6=52.8j

but all the books at ones means, 6*11=66N

and 66*0.8 = 52.8j

Explanation:

The work done is equal..
