As she picks up her riders, a bus driver traverses four successive displacements represented by the expression 126.30 b2 i ^ 2 14.00 b cos 4082 i ^ 2 14.00 b sin 4082 j ^ 1 13.00 b cos 5082 i ^ 2 13.00 b sin 5082 j ^ 2 15.00 b2 j ^ here b represents one city block, a convenient unit of distance of uniform size; i ^ is east; and j ^ is north. the displacements at 40° and 50° represent travel on roadways in the city that are at these angles to the main east–west and north–south streets. (a) draw a map of the successive displacements. (b) what total distance did she travel? (c) compute the magnitude and direction of her total displacement
