Oscillations and mechanical energy

[Knfoster]

Homework Statement

A mass-spring system oscillates with an amplitude of 3.30 cm. If the spring constant is 231 N/m and the mass is 537 g, determine the mechanical energy of the system.

Homework Equations

Mechanical energy is potential energy plus kinetic energy

The Attempt at a Solution

How do I go about starting this problem?

 

[berkeman]

Are you familiar with the equation for the energy stored in a compressed (or extended) spring, in terms of k and delta-x?

 

[Knfoster]

1/2*k*delta x but I'm not given delta x am I? or is the amplitude delta x? and if it is then what do I use for velocity in the 1/2 mv^2 ?

 

[NruJaC]

it's 1/2*k*delta x squared. The max amplitude is your delta x, and since you're considering the situation at max amplitude, the velocity is zero, and so you have just potential energy.

Good luck!
