Answer to Question #136304 in Physics for Melvin Yorke

Question

A ship moves from the Port of Monrovia to the Port of Greenville and from there to the Port of Buchanan. The first displacement vector is 10.2 km due east, and the second is 5.9 km due north. What is the resultant displacement vector?
2. In midtown Monrovia, the street blocks have a uniform size of 80 m x 280 m, with the shortest side oriented at 29 east of north (“uptown”) and the long side oriented at 29 north of west. Suppose you walk three blocks uptown and then two blocks to the left. What is the magnitude and direction of your displacement vector?
3. A sailboat tacking against the wind moves as follows: 3.2 km at 45 east of north, 4.5 km at 50 west of north, 2.6 km at 45 east of north. What is the net displacement for the entire motion?
