A man of mass 83.8 kg stands on top of a uniform ladder whose mass is 11 kg and whose length is 8.7 meters. Find the distance (in meters) from the base of the ladder to the center of mass.(adsbygoogle = window.adsbygoogle || []).push({});

Here's what I did:

X(center of mass) = (83.8*8.7) + (11*0) / (83.8+11)

= 7.69meters

but the correct answer is 8.20meters. What did I do wrong? Please help. Thanks!
