1. A jogger runs directly east for 4 km, then turns and goes northwest for 9 km. He then travels directly south for 5 km. How far is he from the starting point? (km) In what direction is he from the starting point(measured as an angle counterwise from the east axis, units are deg)? (Northwest is the direction lying exactly half way between north and west.) 2. magnitude of displacement= A+B+C 3. I've drawn out the vectors. I'm thinking that I should find the x and y componets of each vector, add the componets, and add the square of the x and y and take the square root. I'm just unsure about how to go about doing this!
