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.
