Find the arc length parameter along the curve from the point where t= 0 by evaluating the integral s = v(t) | dt. Then find the length of the indicated portion of the 0 curve. r(t) = (8 + 3t)i + (4 +7t)j + (7 - 3t)k, - 1sts0 . . .. . The arc length parameter is s(t) = (Type an exact answer, using radicals as needed.)
