A person walks from her home at position O to position F by taking a path that is comprised of three displacement vectors traveled in succession. Vector A with rightwards harpoon with barb upwards on top has a magnitude of 155 m and points 25 degree North of West (above the -x-direction), vector B with rightwards harpoon with barb upwards on top has a magnitude of 92.0 m and points due North, and vector C with rightwards harpoon with barb upwards on top points 50 degree East of North (to the right of the +y-direction) and has a magnitude of 64.7 m.

Calculate A with rightwards harpoon with barb upwards on top times C with rightwards harpoon with barb upwards on top using the components definition.

and C with rightwards harpoon with barb upwards on top cross times A with rightwards harpoon with barb upwards on top
