Spring scales work by measuring the displacement of a spring that supports both the platform of mass mp and the object, of mass m, whose weight is being measured. Most scales read zero when no mass m has been placed on them; that is, they are calibrated so that the weight reading accounts for the mass of the platform mp. Assume that the spring is linear elastic with spring constant k.

Required:
If the mass m is gently placed on the spring scale (it is released from zero height above the scale), determine the maximum reading on the scale after the mass is released.

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
