1.An entrepreneurial new civil engineering graduate started a lab for testing endocrine disrupting compounds.
The lab just broke even the first year, but in years 2 through 5, it made a profit of $97,000 each year. What is the present worth in year 0 of the profit at an interest rate of 10% per year?
2.Plot the relationship between the approach speed v and the length of the dilemma zone for the following data: a2 = 0.5g, ?2 = 1.0s,w = 65ft, L = 15ft, and ? = 4.5s (where a2 is the acceleration, ?2 is the perception reaction time, w isthe width of the intersection, L is the length of the vehicle and ? is the duration of the yellow phase of the traffic signal).
