Question

As she picks up her riders, a bus driver traverses four successive displacements represented by the expression (-7.50 b). (2.00 b cos 40°). (2.00 b sin 40°)j + (5.80 b cos 50。я. (5.80 b sin 50°j. (5.10 b)j Here b represents one city block, a convenient unit of distance of uniform size; î 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.-256, March 1999.">t (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
