if a hammer has a resistance arm of 3 inches and the effort arm is 15 inches. what is the mechanical advantage?

ma = 10
ma = 2
ma = 15
ma = 5

Option D

MA=5

Explanation:

Mechanical advantage is the  the ratio of the output force to the  input force hence

Substituting 15 inches for the effort arm length and 3 inches for the load arm length then we obtain the mechanical advantage as

positive reinforcement? ?

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
