Document Summary
Sketch the vector 2a + b based at the point p and sketch the vector a b based at the point q. P = (3, 1, 2) and q = (2, 2, 0). Suppose that a ball is thrown starting at an initial position r0 = i + 2j + 3k with an initial velocity of v0 = 3i + 4k. Find the position function r(t) for this ball at time t . It will only end in tears. ] (c) compute the curvature of c: (9 points) let c be the ellipse arc length. (x + 2)2. Parameterize c and set up an integral which computes its. |r (t)| (cid:19) t(t) +(cid:18) |r (t) r (t)| r (t) = (cid:18) r (t) r (t) x ds,zc y ds,zc z ds(cid:19) Is this angle right, acute, or obtuse ? (circle your answer. ) (d) match with the correct response:
