A dog in an open field runs 10.0 m east and then 27.0 m in a direction 52.0 degree west of north. In what direction must the dog then run to end up 12.0 m south of her original starting point? How far must the dog then run to end up 12.0 m south of her original starting point? Express your answer with the appropriate units.
Three deer, A, B, and C, are grazing in a field. Deer B is located 61.0 m from deer A at an angle of 50.2 ° north of west. Deer C is located 79.1 ° north of east relative to deer A. The distance between deer B and C is 96.5 m. What is the distance between deer A and C? (Hint: Consider the laws of sines and cosines given in Appendix E.)

1-1 Suppose you want to make a scale model of a hydrogen atom. You choose, for the nucleus, a small ball bearing with a radius of 1.5 mm. The radius of the hydrogen atom is 0.529 × 10−10 m and the radius of the nucleus is 1.2 × 10−15 m. (a) What would be the radius of the model? (b) Suppose that now you want to make a scale model of the solar system using the same ball bearing as...
