The easternmost point in Canada is Cape Spear, Newfoundland, at 82o W. The westernmost point is the Yukon-Alaska border at 141o W. The earth is assumed to be a sphere. of 6400 km radius. Determine the distance from Cape Spear to the Yukon-Alaska border.

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.
