Assignment - Essay Example Where is it at this time? Plan: Remember that gravity is acting against the ball, so the acceleration a = -g = - (constant of gravity near Earth’s surface) = - 9.8 m/s2. Due to gravity, at some point the ball is going to stop (v=0 at the maximum height that the ball reaches) and start to fall back down. We will use +y direction as the up direction. 2b.Next, from the same position, you throw an identical ball (Ball 2) straight down with the same launch speed as in the previous question. How fast will the ball be traveling 2 seconds later and where is it at this time?   The reason for this is that ball 1 reaches its maximum height, then falls back down. When it crosses the point where the platform is, it has the same speed it initially had when thrown up, only now it is going downwards with the same speed. Proof of this: Take ball 1, and find the final speed it would have if the final y value is the same as the initial y value (so that the ball is released from the platform, goes up, and comes right back to the platform). Use the equation vf2 = v02 -2g(yf-y0); the initial and final y values are the same, so their difference is 0 and we have vf2 = v02 -2g(0)= v02 ïÆ' ¨ in other words, vf and v0 have the same magnitudes, but different directions: vf = -v0 3.The ceiling of a classroom is 3.75 m above the floor. A student tosses an apple vertically upward, releasing it 0.5 m above the floor. What is the maximum initial speed that can be given to the apple if it is not to touch the

Is 'gender chaos' an accurate reflection of how the twentieth century Essay

Is 'gender chaos' an accurate reflection of how the twentieth century affected the roles of men and women in African societi - Essay Example With the coming of the colonial government however, these roles came to be directly challenged, as it sought to redesign the African way of life according to its liking. The colonial policies tended to result in chaos between the genders as each strived to maintain the roles that it had traditionally held in the traditional society. Many of the policies that the colonial government instituted were aimed at achieving certain imperial goals but these came to be resisted by the men and women in African societies who felt that their way of life was being threatened by the European colonizers. While the initial response was resistance, this resistance came to fall apart as many African societies either adapted to the European way of life or chose to abandon the gender roles, which they had held in the traditional society. Therefore, it can be said that it is indeed true that gender chaos is a true reflection of how the roles of African men and women were affected in the twentieth century. The colonial policies on various issues came to affect the way men and women in African societies behaved and it can be said that they may have caused gender chaos. The colonial government tended to put limits on some of the traditional practices of African societies in order to achieve one goal or the other. While some of these intentions may have been good, they tended to create a lot of discord in the African communities involved, with some either choosing to ignore the colonial policies while others tended to do it the way they were required, and later do it the traditional way. An example of such colonial policies is given by Lynn Thomas (2003) who in her work states that in order to reduce the instances of abortion in the Meru community in Kenya, the colonial government decided that the age of female excision was to be reduced. This was done because while it was a normal thing within this community for women to have premarital sex, if they became pregnant before excision, the n they were required by their communities to abort the child. This requirement came about because those girls who had not been excised were considered not to be real women and their offspring were considered not to be human but demons. Such forced abortions were believed by the colonial government to be the reason why there were low birthrates among the Meru leading to low population growth. This colonial policy met with resistance from members of the community especially the women, who saw this as a violation of their traditions. While there was compliance with the colonial requirements, the older women in the society and at times the girls involved, often took it upon themselves to do the excision on the girls at the required age, even though these girls had already undergone the operation. The role of women in African societies came to change during the period of the struggle for independence against colonial rule. In many of the African traditional societies, men were the domina nt gender being given preferential treatment in the attainment of all the prominent positions in society. Women, on the other hand, were less visible, often concentrating on the management of their own homes and families. This was the custom throughout most of Africa until such a time as Africa came to be colonized. For several decades after colonization, the role of women in society remained the same but this came to change when some women started gaining the
