One end of a spring whose relaxed length is 0.14 m and whose stiffness is 160 N/m is attached to a wall. The other end of the spring is attached to one end of a straight stiff wire that is 2 m long, and you hold the other end of the wire so that the spring and the stiff wire are approximately horizontal. You pull on your end of the stiff wire so that the spring is 0.17 m long. What is the magnitude of the tension force exerted by the wire on the spring

Answer:

Explanation:

F = kΔx = 160(0.17 - 0.14) = 4.8 N

If all mass is ignored.
