Robert Reid, a 48-year-old African American computer programmer, is 5 feet 9 inches tall and weight 240 pounds. He sits for long hours at work and is too tired to exercise when he gets home at night. His meals usually includes fatty meats, eggs, and cheese, and he likes dairy desserts such as pudding and ice cream. He has a family history of CHD and HTN. His recent laboratory tests show that his blood pressure is 160/100 mmHg, and LDL and HDL levels are 160 mg/dl and 35 mg/dl, respectively. He smokes a pack of cigarettes each day and usually has two glasses of wine at both lunch and dinner.

What dietary changes would you recommend that could help to improve Nr. Reid’s blood pressure and his LDL cholesterol? Explain the rationale for each dietary change. Prepare a day’s menu for Mr. Reid using the DASH eating plan as an outline for your choices?

Jim is a 29 year old computer programmer. He presents today c/o feeling badly for 7-10 days. He states that he has had fever of 100-103 degrees, sore throat and body aches all over. He denies cough, shortness of breath, dysuria or frequency.

Jim says that he is healthy, with no chronic health problems. He has never had surgery. He takes no routine meds. He does not smoke. He has no known allergies. He drinks alcohol 3-4 times per week, 3-4 glasses of red wine. He says that he has done some street drugs, smoking and injecting cocaine. Jim states that he has given up the cocaine, has not used any in 4-6 weeks. He admits to recreational use for only a 3 month period earlier this year, with the last episode being 4-6 weeks ago.

Jim is single. He and his girlfriend of 4 years broke up about 6 months ago and he has had unprotected intercourse 3 times since then with different partners.

Two particles approach each other with equal and opposite speed v. The mass of one particle is m, and the mass of the other particle is nm, where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown above. After the collision the first particle moves in the exact opposite direction with speed 2.40v, and the speed of the second particle is unknown. What is the value of n?

During a hockey match, Jordan slips and crashes into the goalie who is initially motionless. Jordan grabs onto the goalie so they slide together after the collision. Jordan has a mass of 86 kg and the goalie has a mass of 95kg. If the two hockey players are sliding at 2.9 m/s after the collision, how fast was Jordan sliding before the collision? Friction and air resistance may be neglected.

A researcher randomly assigns five individuals to receive a new experimental procedure, measuring number of decision-making errors before and after the procedure. Baseline scores were 7, 6, 9, 7, and 6. Scores after the experimental treatment were. 5, 2, 4, 3, and 6. Conduct a two-tailed hypothesis test with α = .05, being sure to specify the null and alternative hypotheses.
