1. The problem statement, all variables and given/known data You are given Force as a function of distance (F vs x). Find the change in kinetic energy from $x=a $ to $x=b$. 2. Relevant equations see attempt solution conservation of energy equations 3. The attempt at a solution Since F = -dU/dx we get the integral of F = U. Then do U(b)-U(a) to get the answer. Is this right?
