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 60.0Β°, (b) 75 m/ s at 5Ο/ 6 rad, (c) 254 lb at 325Β°, (d) 69 km at 1.1Ο rad.
