Problem 2.102

Two students are on a balcony a distance h above the street. One student throws a ball vertically downward at a speed v0; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in terms of v0, g, h, and t. (a) Write the kinematic equation for the y-coordinate of each ball. (b) Set the equations found in part (a) equal to height 0 and solve each for t symbolically using the quadratic formula. What is the difference in the two balls time in the air? (c) Use the time-independent kinematics equation to fi nd the velocity of each ball as it strikes the ground. (d) How far apart are the balls at a time t after they are released and before they strike the ground?

APRIL 12 2016 INTRO TO SOCIOLOGY PERSPECTIVES ON GENDER  EVERY SOCIETY IN HISTORY HAS BEEN PATRIARCHIAL. THIS MEANS THAT THERE’S A HIGHER VALUE ON BEING A MAN AND ON MALE BEHAVIOR. ***EXCEPTIONS INVOLVE SOCIETIES OF TRIBAL CULTURES, VERY RARE.  FUNCTIONALIST o WHY THERE HOW DOES SOCIETY BENEFIT o THE MOST SUCCESSFUL FAMILY MODEL IN PRIMITIVE TIMES WAS ONE PARENTS AS A PROVIDER AND PROTECTOR WHILE THE OTHER WAS A CAREGIVER. THE MAN WAS CHOSEN AS THE PROVIDER BECAUSE OF HIGHER BODY STRENGTH, SO GENDER INEQUALITY DEVELOPED BECAUSE IT WORKED. o THIS MODEL IS STILL THE BEST IN MODERN TIMES. BUT, GENDER IS MORE IRRELEVANT IN REFERENCE TO ROLE CHOICE. PROVIDING AND PROTECTING NOW EQUATES TO EARNING MONEY VIA A CAREER. AMONG MARRIED MALE/FEMALE COUPLES, 1/3 FEMALES EARN MORE THAN THEIR HUSBANDS.  CONFLICT o GENDER INEQUALITY FROM AN ECONOMIC STANDPOINT: ECONOMIC REDUCTIONISM. o ANYTIME YOU CAN DISCRIMINATE AGAINST A GROUP, IT’S FOR PROFIT. THERE IS PROOF IN THE WAGE GAP, WHICH IS A SYSTEMATIC DISCRIMINATION AGAINS FEMALES AND IS STILL WIDESPREAD. WE KNOW THAT PAY RATE DISCRIMINATION IS ILLEGAL BUT THE DISCRIMINATION OCCURS IN JOB CATEGORIES. TRADITIONAL FEMALE OCCUPATIONS (NURSING, TEACHING, SOCIAL WORK) ARE LESS PAID THAN TRADITIONAL MALE OCCUPATIONS. o COMPARABLE WORTH LAWSUITS HAVE RISEN BECAUSE OF THIS ISSUE.  FUNCTIONALIST CRITIQUE OF WAGE GAP o MEN PUT IN MORE TIME AT WORK THAN THE AVERAGE WOMAN o OCCUPATIONAL CHOICE WOMEN TEND TO CHOOSE JOBS WITH LOWER PHYSICAL RISK, BETTER WORKING CONDITIONS, AND MORE REGULAR HOURS. MEN CHOOSE HEAVY PHYSCIAL LABOR LIKE CONSTRUCTION, OUTDOOR WORK, OVERNIGHT WORK (HIGHER COMPENSATION), AND MORE DANGEROUS WORK. o MATERNITY LEAVE MANY WOMEN TERMINATE EMPLOYMENT TO BE A FULLTIME MOM. WOMEN ARE MORE LIKELY TO FACE CAREER INTERRUPTIONS, WHEN REENTERING THE CARRER, THEY HAVE TO START AT THE BOTTOM AGAIN. WHILE IN THEIR 20S, WOMEN EARN 8% MORE THAN MEN. AFTER, WAGE GAP BEGINS.  FEMINIST THEORY o AGREE WITH CONFLICT, BUT CONFLICT LEAVES OUT HALF: NOT JUST ECONOMIC, ALSO INTERPERSONAL IN HOW MALES VS. FEMALES ARE RAISED. o MEN AND WOMEN ARE RAISED TO ACCCEPT MALE SENSE OF ENTITLEMENT (TO REGARD AS A RIGHT THAT WHICH OTHERS REGARD AS A PRIVILEGE) o FOR EXAMPLE, MEN AFTER THANKSGIVING DINNER LEAVE TO WATCH TV. IF ASKED TO CLEAN THE DISHES, THEY FREAK. WOMEN, ON THE OTHER HAND, CONGREGATE TO CLEAN, BUT IF ASKED TO WATCH TV GET EXCITED LIKE WOAH. FEMALE INFANTS GET MORE PHYSICAL AFFECTION BUT ARE MORE PROTECTED AND MALE INFANTS ARE ALLOWED AND ENCOURAGED TO EXPLORE AND CRY LONGER. THIS CARRIES OVER TO THE TEEN YEARS. BOYS ARE ALLOWED TO STAY OUT LATER AND MORE LIKELY TO USE THE CAR. GIRLS’ PARENTS ARE SUPER PICKY ABOUT DATING PARTNERS MORE THAN BOYS. o ARGUES FOR SAME RAISING METHOD OF GIRLS AND BOYS.  3 AGENTS OF SOCIALIZATION THAT ENCOURAGE ENTITLEMENT o THE FAMILY BECAUSE OF UPBRINGING, MALES TURN TO SELF-SUFFICIENT INDEPENDENT BEHAVIOR WHILE WOMEN BECOME DEPENDANT-ORIENTED, GIVING WAY TO MALE ENTITLEMENT o EDUCATIONAL SYSTEM AND GENDER TRACKING MEN ARE STEERED TO HIGHER OCCUPATIONS WHILE WOMEN TOWARDS TRADITIONAL FEMALE ROLES. AMPTITUDE TESTS o MASS MEDIA AND STEREOTYPING OF WOMEN 1. A WOMAN IS A HOMEMAKER 2. A WOMAN AS A SEX OBJECT 3. A WOMAN AS A SUPERMOM: IN CHARGE OF FAMILY WHILE HAVING A HIGH-POWER CAREER. SHE SETS EXPECTATIONS WAY TO HIGH. 2 AGING PROCESS, QUALITIES  THE GRAYING OF AMERICA our population transformed in the US because of the baby boom following WWII. Now, we have a far greater proportion of people over age 65 in the population. In 1900, 1/30 people were age 65+. In 2010, 1/8 people were age 65+. In 2030, estimated 1/5 are age 65+. Strains Produced: 1. Structural Issues these emerge because of older people. In services, aging creates an imperative for rapid treatment. For example, hospital care now has a “revolving door” model in that you’re in and out as fast as possible because of high demand. With more old people, more medical needs need to be serviced. In institutions, residential care centers have been created and in-home health care has emerged. With social programs, things like medicare and social security were created. It’s predicted that social security will go bankrupt in 2037; the US is even in deficit this year. They’re very expensive programs: there are about two full-time workers for every social program recipient. 2. Interpersonal Issues the change in proportion created younger people being more resentful, hostile, and even discriminatory towards the elderly.  Another issue is simply in aging. When aging, disengagement (withdrawal of someone from personal and professional interaction) becomes common. There are three key perspectives on disengagement. o Voluntary Disengagement E. Cummings chooses to withdrawl because content with contribution to society. APRIL 12 2016 INTRO TO SOCIOLOGY PERSPECTIVES ON GENDER  EVERY SOCIETY IN HISTORY HAS BEEN PATRIARCHIAL.
