An object vibrates at the end of a horizontal spring (k=955 N/m) along a frictionless surface. The speed of the object is 0.250 m/s when its displacement is 0.145 m. What is the maximum displacement of the object if its maximum speed is 0.322 m/s?
I understand to find max displacement, you use the formula:
Et=1/2kA^2
Now that you have to find Et, you can't use teh formula Et=1/2mvo^2. or can't find Ek, as you don't have the mass.
Can someone please tell me how to find Et. tahnks.
