CAN SOMEONE PLEASE SHOW ME HOW TO DO THIS IM CONFUSED!!!!!

Mathematics
1 answer:
Mnenie [13.5K]3 years ago
8 0

Answer:

D. 160J

Step-by-step explanation:

Work = Force * Distance

but where is the force?

from here:

weight (not mass) is a force unit (Newtons) so it can be used here.

How do we get weight?

Mass * G

what is G?

gravity force... and it equals 9.8

so you take the box's mass (9.10)

multiply by 9.8 (9.10*9.8 = 89.18)

then plug into the first equation as the force (work= 89.18 * distance)

we also plug In the distance (work = 89.18 * 1.8)

and solve for work! (work = 89.18 * 1.8 = 160.52400)

then round the to the closest one (160)

and there you go! you've got your answer!

Hope this helps,

Yotam

P.S you can comment back if you are still confused and I will try to explain it again better.
