(adsbygoogle = window.adsbygoogle || []).push({}); Two people are holding up the ends of a 4.70-kg wooden board that is l = 1.80 m long. A m = 8.00-kg box sits on the board, 0.50 m from one end, as shown below. What forces do the two people exert?

Fright person = ?

Fleft person =?

Okay so this is what i did:

I drew a diagram and found out that each half of the board is 0.9 m. The box is 0.5 m away from the end of one side, so i subtracted 0.5 m from 0.9, which left me 0.4 m from the box to the center of gravity.

4.7 + 8 = 12.7 kg <---Total

1.8-0.5=1.3

0.9(4.7)+1.3(8)=14.63

14.63=1.8x

=8.13 N

To find one side I did:(I think it's left, but i put in the answer for both sides anyway)

12.7-8.13=4.57

It was of course, marked wrong. I redid it to see if i might've typed something in my calculator wrong...everything was "right"...meaning I did the whole process completely wrong.

Thanks in advance for your help!
