Let a be the last digit, let b be the second to last digit, and let c be the sum of the last three digits of your 8-digit student id. example: for 20245347, a = 7, b = 4, and c = 14. starting from rest, a student pulls a (25.0+a) kg box a distance of (4.50 + b) m across the floor using a (134 + c) n force applied at 35.0 degrees above horizontal. the coefficient of kinetic friction is 0.220 between the floor and the box. find the work done by the pulling force. give your answer in joules (j) and with 2 significant figures. slader

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?

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

As microwave light travels through a liquid, it moves at a speed of 2.2 x 108 m/s. if the frequency of this light wave is 1.1 x 108 hz, what is the wavelength of this microwave?
