Recall that the spring constant is inversely proportional to the number of coils in the spring, or that shorter springs equate to stiffer springs. an object is attached to the lower end of a 14-coil spring that is hanging from the ceiling. the spring stretches by 0.174 m. the spring is then cut into two identical springs of 7 coils each. as the drawing shows, each spring is attached between the ceiling and the object. by how much does each spring stretch?

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
