I tried the formula (Sum of all)F= ma but the answer isn't 1!! What is the reading on the scale if the system is in equilibrium. Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. As you can see, is not equal to the weight. The grapes oscillate up and down with a period of 0.48 s, and the spring in the scale has a force constant of 650 N/m. 17.
