A scout walks 8.5 km due east from camp, then turns left and walks 7.65 km along the arc of a circle centered at the campsite, and finally walks 2.55 km directly toward the camp. (a) How far is the scout from camp at the end of his walk? V km (b) In what direction is the scout's position relative to the campsite? 37 ° (clockwise from north) (c) What is the ratio of the final magnitude of the displacement to the total distance walked? 1 Sketch the path walked by the scout. To determine the final distance of the scout from the camp, you will need to determine the angle subtended by the circular arc segment of the ccout'c path

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
