The diagram below shows a sled moving along a smooth, frictionless track. In which sections of the track will the sled experience an unbalanced force?

Answer 1

Without a diagram attached, it is not possible to determine the specific sections of the track where the sled will experience an unbalanced force. However, in general, an unbalanced force will occur when there is a net force acting on the sled. This can happen when there is a difference in the forces acting on the sled in different directions or when there is a change in the magnitude of the force acting on the sled.
