A cat is brought into a vets office you need to find itscenter of gravity. You place its front legs on a scale thatreads 89N and hang its back legs so that the catis horizontal on a hanging scale that reads 157N. Thedistence between the cats front feet and back feet is .95meters.
A) calculate the center of gravity.
B) what is the total weight of the cat?
