Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke's law. In laboratory tests on a particular tendon, it was found that, when a 0.255 kg object was hung from it, the tendon stretched 1.25 cm Part A Find the force constant of this tendon in N/m Express your answer in newtons per meter. Part B Because of its thickness, the maximum tension this tendon can support without rupturing is 145 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Express your answer in centimeters. Part C Express your answer in joules.

Consider the figure above, where a rigid beam of negligible mass and 10 m long is supported by a cable attached to a spring. When NO block is hung from the beam, the length L (cable-spring) is equal to 5 m. Assume that immediately after block (weight of 260 N) is hung at the end of the beam the spring does not stretch, calculate the tension under this assumption. Using this tension find how much the spring stretches. Express the amount the spring is stretched in cm. k =8275 N/m.
