The vertical transmission of certain communicable diseases from mother-to-child during pregnancy and birth is of great concern to public health practitioners because it represents a critical period for intervention. If practitioners can determine at birth whether the disease has been transmitted from mother-to-child, they can act immediately to provide the child with treatment. Syphilis is a disease with high risk for vertical transmission from mother-to-child. If a child becomes infected and is not treated, there can be negative health outcome such as blindness, deafness, and neurological damage. Inspired by the advent of rapid HIV tests that provide quick results and are minimally invasive, suppose that researchers have been working to develop a similar test that can be used for syphilis. After obtaining appropriate institutional approval and patient consent, the researchers test their rapid syphilis test at several birthing hospitals and compare it to the gold standard laboratory test. A total of 77 samples are collected from infants at the time of birth. The gold standard identifies that 45 of the 77 tests were negative but the rapid test show 63 negative results. Of these 63 negative rapid test results, 43 are confirmed to be true negatives.

Problem 5. You and your bicycle have a combined mass of 80.0 kg. When you reach the base of a hill, you are travelling at 5.00 $\frac{m}{s}$. Reaching the top of the hill you have climbed a vertical distance of 5.20 m and have slowed down to 1.50 $\frac{m}{s}$. You can ignore the work done by friction and any inefficiency in the bike. (a) What is the total work done on you and your bike during this climb? (b) How much work have you done with the force you applied to the pedals? Problem 6. A man pushing a crate of mass $m = 92.0$ kg at a speed of $v = 0.850 \frac{m}{s}$ encounters a rough horizontal surface of length $l = 0.65$ m. The coefficient of kinetic friction between the crate and the rough surface is 0.358 and the man exerts a constant horizontal force of 275 N on the crate. (a) Find the magnitude and direction of the net force on the crate while it is on the rough surface. (b) Find the net work done on the crate while it is on the rough surface. (c) Find the speed of the crate when it reaches the end of the rough surface.

Choose your own monetary policy adventure! 1. Imagine that either the economy is in an expansion or a recession. In the next few prompts you will talk about responding to this situation, so choose wisely. This choice is yours to make, so please now state what is going on with the economy you are pretending to observe. 2. Would you use expansionary or contractionary policy to help the economy? 3. Why would you use the policy you mentioned in 2 above (i.e. what are you trying to affect or prevent)? 4. What changes could you make to reserve requirements, the discount rate, and in open market operations that could help you pursue the policy that is appropriate for the situation the economy is in? 5. How will the changes mentioned in 4 actually help the economy? In other words, how will the changes you want to make translate into real people making different decisions that will ultimately help the overall economy? You probably want to mention how the market for money is affected, how the interest rate might change, how people respond to changes in the interest rate, and how this behavioral change in many people can change the overall economy.
