1. Jarak di antara titik A(5,0) dengan titik B(b, 0) ialah 4 unit. Cari nilai yang mungkin bagi b The distance between point A(5.0) and point Bib, 0) is 4 units. Find the possible values of b.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
