A 12 N package of flour is suddenly placed on the pan of a grocer's scale. The pan is supported from below by a vertical spring
Licemer1 [7]

Answer:

  24/325 m ≈ 7.38 cm

Step-by-step explanation:

The equilibrium position of the package is the distance at which the package weight is balanced by the spring force. That distance is ...

  (12 N)/(325 N/m) = 12/325 m

Since the package is placed suddenly on the pan and there are no losses in the system, the position of the package will oscillate about this distance with an amplitude equal to this distance. That is, the maximum compression will be to a distance that is twice this amount, or ...

  24/325 m

__

This is the depth at which all of the potential energy of the package due to its height is transformed into the potential energy of the spring due to its compression.

The formula for the hypotenuse of a right triangle with legs of length a and b is shown.
fomenos

Answer: b=\sqrt{c^{2}-a^{2}}

Step-by-step explanation:

To solve the exercise you must solve for b from the formula for the hypotenuse, as you can see below:

- Square both sides of the equation as following:

c^{2}=(\sqrt{a^{2}+b^{2}})^{2}

- Now you must subtract a² from each side of the equation, then you obtain:

c^2-a^{2}=a^{2}-a^{2}+b^{2}

c^2-a^{2}=b^{2}

- Apply square root to both sides:

\sqrt{b^{2}}=\sqrt{c^{2}-a^{2}}

Then:

b=\sqrt{c^{2}-a^{2}}
