Question

Spring scales work by measuring the displacement of a spring that supports both the platform of mass $m_p$ and the object of mass $m$, whose weight is being measured. In your solution, note that most scales read zero when no mass $m$ has been placed on them; that is, they are calibrated so that the weight reading neglects the mass of the platform $m_p$. Assume that the spring is linear elastic with spring constant $k$. If the mass $m$ is gently placed on the spring scale (i.e., it is released from zero height above the scale), determine the maximum reading on the scale after the mass is released.
