well that's all the mastering physics website states as the problem statement. so F=ma so F= mg so mg=-kx so k=mg/x?

yeah I just don't know where to start really. it's F=-kx

Homework Statement If a fish is attached to a vertical spring and slowly lowered to its equilibrium position, it is found to stretch the spring by an amount d. If the same fish is attached to the end of the unstretched spring and then allowed to fall from rest, through what maximum distance...

1. Homework Statement [/b] A block with mass (m) is attached to an ideal spring that has force constant (k) . 2. Homework Equations [/b] a.)The block moves from (x_1) to (x_2) , where (x_2) > (x_1) . How much work does the spring force do during this displacement? b.The block moves...

Homework Statement A baseball is thrown straight up. The drag force is proportional to v^2. In terms of g , what is the y-component of the ball's acceleration when its speed is half its terminal speed and it is moving up? moving back down? Homework Equations F=ma mg+bv^2=ma mg-Bv^2=ma The...
