In action movies there are often chase scenes in which a car becomes airborne. When the car lands, its four suspension springs, one on each wheel, are compressed by the impact. For a typical passenger car, the suspension springs each have a spring constant of about 500 lb/in. and a maximum compression of 6 in. Using this information, estimate the maximum height from which a 3300 lb car could be dropped without the suspension springs exceeding their maximum compression. Assume that the mass of the car is distributed evenly among the four suspension springs.

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 )
3.37(a) Five free electrons exist in a three-dimensional infinite potential well with all three widths equal to \( a = 12 \, \text{Å} \). Determine the Fermi energy level at \( T = 0 \, \text{K} \). (b) Repeat part (a) for 13 electrons.
