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.

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^

hypothesising or postulating

force tends to be low and long diustance masses are high

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
