Question

EXACTLY ANSWER PLEASE, 5 STARS ;)

You take your dog Clea to the vet, and the doctor decides he must locate the little beast's center of gravity. It would be awkward to hang the pooch from the ceiling, so the vet must devise another method. He places Clea's front feet on one scale and her hind feet on another. The front scale reads 155 N while the rear scale reads 80N . The vet next measures Clea and finds that her rear feet are a distance 0.86 m behind her front paws.

A-)How much does Clea weigh?

B-)Where is her center of gravity?(behind her front paws)

Explanation / Answer

A) Total weight = 155 N + 80 N = 235 N

Consider the dog as two balls attached to a rod one ball(front feet) and another(hind feet). So this answer

B) distance between the feet = 0.86 m

From the center of gravity lets assume x be the distance of front and 0.86 - x of the hind feet

So , x * 155 = 80 * (0.86 - x)

x = 0.293 m
