A 54 kg pilot flies a jet trainer in a half vertical loop of 1200 m radius so that the speed of the jet decreases at a constant rate. Knowing that the pilot's apparent weights at points A and C are NA = 1680 N and NC = 350N, respectively, determine the total force exerted on her by the seat of the jet trainer when the trainer is at point B.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
