I. A Mac Truck starts from rest and reaches a speed of 8.5 m / s in 20 seconds. II. A dune buggy travels for 20 seconds at a speed of 8.5 m / s.

III. A driver sees a deer in the road ahead and applies their brakes. The car slows to a stop from 8.5 m / s in 20 seconds.

A. For each of the three above problems, say whether CVPM applies and explain your reasoning.

B. Choose one of the problems for which CVPM applies. For the problem you selected, draw at least three diagrams and or graphs to illustrate the situation. Choose the diagrams and graphs that you can find most useful.

C. Using the constant velocity particle model, solve for any unknown quantities. Show your work and use units!

Please help, I don’t understand at all! Please show work as well!!!

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
