Answer to relevant QuestionsWhen you are riding in a fast-moving car, in what direction would you throw an object up so it will return to your hand? Explain. A hot air balloon rises vertically with a speed of 1.5 m/s. At the same time, there is a horizontal wind blowing. In which direction is the balloon moving? (a) Is vector addition associative? That is, does (A-bar + B-bar) + C-bar = A-bar + (B-bar + C-bar)? (b) Justify your answer graphically. Two vectors are given by A-bar = 4.0 X-bar – 2.0 y-bar and B-bar = 1.0 x-bar + 5.0 y-bar. What is (a) A-bar + B-bar, (b) B-bar – A-bar, and (c) A vector such that A-bar + B-bar + C-bar = 0? Referring to the parallelogram in Fig. 3.29, express C-bar, C-bar – B-bar, and (E-bar – D-bar + C-bar) in terms of and B-bar.
