The rules for the shot put specify that the circle from which the shot-putter puts the shot must be only 7 ft 6 in. in diameter. The athlete may not allow any part of his or her body to touch anything outside of the circle during the throw. If the throwing circle were enlarged to be 10.0 ft in diameter, would performances in the shot put improve or decline? Why?

His performance would improve

Explanation:

This is because, he now has a larger distance to cover in the 10.0 ft diameter circle. This increased distance would cause him to give a greater angular speed to his whirl and thus a greater tangential velocity to the shot put. This greater speed would thus cause the shot put to travel more in the 10.0 ft diameter circle throw than in the 7 ft 6 in diameter circle throw.

The performance will improve because more energy will be expended on the shot

Explanation:

The performance in the shot put is the work done or the energy expended by the short putter

Work done = Energy expended = Force applied by the short putter * displacement

When the diameter of the shot = 7ft 6 in = 7.5 ft

Work done = 7.5 * Force

When the diameter of the shot = 10 ft

Work done = 10 * force

Since the circle is enlarged, shot putter will be able to do more work on the shot, causing an increase in the expended energy, hence an improvement in performance

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
