|| A 2 kg block is launched up a frictionless inclined plane by a spring as shown in Figure 5.64. The plane is inclined at 30° and the spring constant is 1000 N/m. The block is initially pushed against the spring in order to compress the spring 0.1 m, and then it is released. (a) Calculate the magnitude and direction of the acceleration of the block the moment after it is released. (b) Calculate the acceleration when the spring reaches the point where its compression is 0.05 m. (c) What are the magnitude and direction of the acceleration when the spring reaches the point where its compression is zero? Figure 5.64 Problem 57.

Use the following information to answer the next question.
Two mirrors meet an angle, a, of 105°. A ray of light is incident upon mirror A at an angle, i, of
42°. The ray of light reflects off mirror B and then enters water, as shown below:

6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter
and with 10 mm thickness. 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. In OpticStudio, create a default merit function optimizing on spot size.Then insert
one extra line at the top of the merit function. Assign the…
