Homework Equations


Emec - PE = KE

The Attempt at a Solution


When particle starts at x = 4 KE = .5(.25)(225) = 28.125
Energy of system = 28.125
I don't have anything with position here so i am unsure how to find what position that the energy will be equal to the Emec and turn the particle around

I think i need to use force here and force is dPE(X)/dx
