An athlete puts a 16-lb shot at an angle of 45 to the horizontal from 6 ft above the ground at an initial speed of 39 ft/sec. How long after launch and how far from the athlete does the shot land? The shot remains in the air for |seconds. (Round to two decimal places as needed.) The shot travels |feet. (Round to two decimal places as needed.)I Find the arc length parameter along the given curve from the point wheret= 0 by evaluating the integral s(t) = Ilv(r)| d't. Then find the length of the indicated portion of the curve r(t)= Beast i+ 85in t j + 3t k, where 05 ts 0 The arc length parameter along the curve, starting at t = 0 is 5(t) = m . (Type an exact answer, using radicals as needed.) 4a 2 (Type an exact answer, using radicals and TE as needed.) The length of the indicated portion of the curve is L = 1: . Nla
