Your dog Nikita is 0.740 m long (nose to hind legs). Her forelegs are 0.15 m horizontally from her nose, her center of gravity is 0.15 m horizontally from her hind legs, and she weighs 220 N.

(a) How much force does a level floor exert on each of Nikita's forefeet and on each of her hind feet?

(b) If Nikita picks up a 25 N bone and holds it in her mouth (directly under her nose), what is the force exerted by the floor on each of her forefeet and each of her hind feet?
