A child is pushing a merry-go-round. The angle through which the merry-go-round has turned varies with time according to u1t2 = gt + bt 3 , where g = 0.400 rad>s and b = 0.0120 rad>s 3 . (a) Calculate the angular velocity of the merrygo-round as a function of time. (b) What is the initial value of the angular velocity? (c) Calculate the instantaneous value of the angular velocity vz at t = 5.00 s and the average angular velocity vav@z for the time interval t = 0 to t = 5.00 s. Show that vav@z is not equal to the average of the instantaneous angular velocities at t = 0 and t = 5.00 s, and explain.

IowaNH New campaigning styles decrease the importance of winning Iowa and New Hampshire Michael C. Bender, Jan 25/16 “Trump Upends New Hampshire Tradition of Retail Politics” http://www.bloomberg.com/politics/articles/2016-01-25/trump-upends-new- hampshire-tradition-of-retail-politics In one of the many jokes about New Hampshire that U.S. Senator John McCain likes to tell, one voter asks another for thoughts about a presidential candidate. “I don’t know,” the second voter says. “I’ve only met him twice.” “That's been the reality of winning a primary in New Hampshire,” McCain said about the joke in an interview. “Up until this campaign, they want to have contact with the candidate.” What's new this campaign, of course, is Donald Trump, who has eschewed t
