A constant force Fx = 6N is in the +x direction. A) Find the potential energy function U(x) associated with this force if U(Xo) = 0. B) find a function U(x) such that U(4.0m) = 0 C) Find a function U(x) such that U(6.0) = 14J I know that if PE is known then the F can be found by the derivative of the PE. I know that if F is known then the PE can be found by integrating the force. Since the force Fx is given to be 6N the integral of 6 = -6x + C Is that PE function for the force Fx? Im not sure what A means but is B 0 = -6(4) + C C = 24? and C is 14 = -6(6) + C C = 50 Thanks for your help.
