Textbook Question
Chapter 9, Problem 4EP
Verify that your equation has the masses and the velocities before and after the collision. If not, review your result with a classmate or your instructor. Solve the equation for the initial velocity of the projectile, vo.
Note that to calculate the initial projectile velocity vo, the velocity V of the block and projectile combination needs to be known. (The values of the masses can be determined with a balance.) So far, only one conservation principle has been used—the conservation of linear momentum. Now consider the mechanical energy of the system after the collision. Write an expression for the kinetic energy of the system (the mass and bob combo) immediately after collision, and label it Eq. 2.
As the bob swings upward from h1 to a maximum height h2 (GL Fig. 9.1), what is happening to the kinetic energy of the system (neglecting friction)?
If the kinetic energy is decreasing, is there another form of mechanical energy in the system that may be increasing? If so, what is it?
Write an equation for the mechanical energy of the system at h2, and call it Eq. 3.

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 )

Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens.
