... Answer: The acceleration is negative. In 1D, F = - dU/dx. The slope of the curve dU/dx is positive at x=A, so F = ma = -dU/dx is negative there. The force F and the acceleration a = F/m are negative at x=A (meaning their directions are to the left, toward negative x.) The kinetic energy might be zer ...
