## Question:

You have a spring that has a mass of 100 g and a constant of 22 N/m with an amplitude of 5 cm. Find the total energy, the max velocity, and the max force.

## Hooke's Law:

The forces on a spring may follow Hooke's law. This law states that the force that will compress or stretched the spring is negatively proportional to the displacement of the spring by a constant referred to as the spring constant. The direction of the force is always opposite to the direction of the motion.

(A) The total energy of the spring is given as:

{eq}E_t = \frac{1}{2}kA^2 {/eq}

where:

A is the amplitude

k is the spring constant
