The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Textbook Question

Chapter 5, Problem 62GP

The drag force is an important fact of life for the small marine crustaceans called copepods. The drag force for small objects in water is very different from the drag force in air, so the drag equations of this chapter don’t apply. However, we can estimate the drag force from data. The velocity graph of Figure P5.62 shows two phases of the swimming motion of a 1.8 mg copepod. First it swims vigorously, speeding up; then it stows down under the influence of drag. What is the magnitude of the drag force? What is the ratio of the drag force to the copepod’s weight?

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )
