A relaxed spring of length 0.18 m stands vertically on the floor; its stiffness is 1130 N/m. You release a block of mass 0.6 kg from rest, with the bottom of the block 0.4 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring

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
