Evaluate the flux integral F . ds, where F(z,y, 2) = (3ry, x cos(2), 2 ) and S is the complete boundary surface of the solid region bounded by the cylinder y? + 22 = 2 and the planes r = 1 and x = 3. S is oriented by the outward normal. A. 97 B. 127 C. 147 D. 187 E. 247 20. The position function of a Space Shuttle is r(t) = (t?, -t, 6), t 2 0. The International Space Station has coordinates (16, -5, 6). In order to dock the Space Shuttle with the Space Station the captain plans to turn off the engine so that the Space Shuttle coasts into the Space Station. At what time should the captain turn off the engines? Assume there are no other forces acting on the Space Shuttle other than the force of the engine. A. 6 B. 8 C. 2 D. 4 E. 0 11
