The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.

Answer:
Employment, property and family law.
Explanation:
The ERA has to be considered in its historical context. It was first proposed in 1923, at a time where women had little or no rights regarding work and payment and faced discrimination. The ERA proposed a total abolition of law discrimination based on sex, which would have been revolutionary at the time. Later, during the 1960s and 1970s when the ERA was again discussed, some of the problems were solved with other laws, like the Equal Pay Act or the Civil Rights Acts. However, while these acts are a key part of American Legislation, the ERA is a Constitutional Amendment, which would give a completely new level of protection.
There is criticism, mainly because many of the laws and guarantees gained during the past 100 years have been tailored to protect women in their specificity. And many fear that the ERA would negatively override those protections. However, as an Amendment, any discrimination based on sex could be challenged based on unconstitutionality. And as of now, women still suffer discrimination and the acts and laws enacted so far are not sufficient.
