Example 2: Calculating Time from Power A typical healthy adult human can provide 150 W of output power. You have
to push a 65 kg box of cereal (at rest) along the floor, and the coefficient of
friction with the floor is 0.37 (your shoes have a coefficient of friction of 0.84
with the floor). How much time should it take you to push it 3 m along the
floor at maximum power? Assume you push at constant speed after initially
starting to move it.

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
