Wind Velocity Problem: A navigator on an airplane knows that the planes velocity through the air is 250 km/hr on a bearing of 237. By observing the motion of the planes shadow across the ground, she finds to her surprise that the planes ground speed is only 52 km/hr and that its direction is along a bearing of 15. She realizes that the ground velocity is the vector sum of the planes velocity and the wind velocity. What wind velocity would account for the observed ground velocity?
Study Guide 1. How does parent-adolescent conflict change over time (i.e., as adolescents get older) What reasons underlie these developmental changes Under what conditions is parent adolescent conflict most common Early adolescents: high conflict btw mothers and daughters, high if martial relationship is distressed and is MORE “intense” during mid adolescence It then diminished in late adolescents and emerging adulthood. The reasons they conflicts occur are the biological changes (puberty, height, sex), cognitive changes (perspective taking), and the adolescents desire to autonomy. Individualistic cultures show more parental conflict 2. Discuss three reasons why families experience disequilibrium when a child in the home is transitioning to adolescence. During adolescence, sometimes a family may feel a sense of disequilibrium that they will have to adjust to. Some of these reasons may include mood changes in the adolescent, the dating and sex they may be engaging in, and puberty. 3. Describe the three primary changes in peer relationships that occur during adolescence; be sure to describe research findings that support each one. From childhood to adolescences, there are a few different things that change in what is sought after in a friendship. During adolescences, one finds the addition of intimacy, trust, and loyalty to be a must. 4. Describe how friendships (NOT broad peer relationships) change in adolescence and WHY these changes occur. 5. Define and contrast cliques versus crowds. How are they defined, and what is their purpose (i.e., what do they pr
