I know that total energy= 1/2 k A^2. I tried to solve for total energy and then using E= K+U and rewriting E= 1/2 m w^2 + 1/2 k x^2. I come out with an energy from the first equation and then try to solve for x using the second equation. I don't think that is the right approach.
Homework Statement
If you have a simple harmonic oscillator based on a spring of force constant 5.79 N/m, with an attached mass of 0.828 kg, and the oscillator is initially displaced 3.5 cm from equilibrium, at what distance from the equilibrium point (in cm) will the oscillator have equal...
The toy car is sliding with a kinetic energy of 6.4 J when it locks up its tires (obviously, the toy driver slammed on the toy brakes) and slides for 62 cm, while a frictional force of 0.63 N acts against it. What is the kinetic energy (in Joules) of the car after this frictional work is done...
