a) w = 873 rev, b) θ = 97.75 rev

Explanation:

This is a rotation kinematics exercise

w = w₀ + α t

θ = θ₀ + w₀ t + ½ α t²

let's start by reducing the magnitudes to the SI system

w₀ = 300 rpm (2pi rad / 1 rev) (1 min / 60s) = 31.42 rad / s

α = 6 rad / s²

a) let's look for the angular velocity

w = 31.42 + 6 10

w = 91.42 rad / s

b) θ₀ = 0

θ = 0 + 31.42 to + ½ 6 10²

θ = 614.2 rad

As they ask for the result in rpm and revolutions, let's carry out the reduction

w = 91.42 rad / s (1 rev / 2pi rad) (60 s / 1min)

w = 873 rev

θ = 614.2 rad (1 rev / 2pi rad)

θ = 97.75 rev

Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colourless liquid organic compound with the chemical formula ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called glacial acetic acid. vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. it is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7 3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366 chemblchembl539 chemspider171 drugbankdb03166 echa infocard100.000.528ec number200-580-7e numbere260 (preservatives)gmelin reference1380iuphar/bps1058keggd00010 meshacetic+acidpubchem cid176rtecs numberaf1225000uniiq40q9n063p un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4) key: qtbsbxvteameqo-uhfffaoysa-n smilescc(o)=o

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
