A hockey stick exerts an average force of 39N on a 0.2kg hockey puck over a displacement of 0.22m. if the hockey puck started from rest‚ what is the final velocity of the puck? Assume no friction. Your physics teacher walking with the aid of a cane approaches a skateboard of 3.5 kg lying on the side walk. Pushing with an angle of 60 degree down from the horizontal with his cane‚ he applies a force of 115N‚ which is enough to toll the skateboard out of his way. Calculate the initial acceleration

Pearl’s Force of Nature The force of nature is powerful and cannot be escaped or denied. It is everywhere‚ and it is often used to symbolize many different ideas‚ such as birth‚ freedom‚ and change. The idea of nature as an important symbol is prominent in Nathaniel Hawthorne’s The Scarlet Letter. In the novel‚ Hester Prynne is marred with the red letter A‚ for adulteress‚ on her breast for all of her life. A result of her sin‚ was the birth of her daughter‚ Pearl. Pearl is often thought to be a

have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the strong force fades away abruptly and dramatically outside

Porter’s Five Forces 1 In talking strategy for any company‚ Porter’s Five Forces Model is likely to come up. It has served as a strategic planning guideline for years. If a company is just starting out‚ they would have to analyze the model and apply it to themselves from every aspect. If a company is well established‚ the model can serve as points that need to constantly be revisited. In going global‚ the tool becomes invaluable. It still only serves as a guideline‚ but it delivers significant

FORCES FOR STABILITY AND CHANGE Forces for Stability Organizational forces exist that provide continuity in form and function over time for survival of our system. These forces produce institutional power. Examples include: • Specialization • Continuity of roles • Predictable results • Sophistication • Maturity of key parts of the organization • Confidence in taking risks with known problems Clues that these forces are at work:

Global forces at Pilkington The early 21 century continued to provide tough challenges for manufacturing organization based in developed economies. This was particularly true for manufacturing of basic materials such as steel or glass as they experienced fierce competition around the world. Pilkington based in St Helens‚ U.K.‚ started glass manufacturing in 1826. But the major breakthrough for the company was the development of the float glass manufacturing process‚ announced in 1959.

Porter’s Five Forces A competitive strategy must meet the opportunities and threats inherent in the external environment; it should be based on an understanding of industry and economic change. Porter identifies five forces that shape every industry and which determine the intensity and direction of competition and therefore the profitability of an industry. The objective of strategic planning is to modify these competitive forces such that the organization’s position is improved. Management

experimented for the equilibrant force‚ conditions and center of gravity. Our results showed consideration as to disregarding other forces than weight and tension. 1. Introduction Equilibrium is a state of balance in which it is a condition where there is no change in the state of motion of a body. Equilibrium may be observed on objects which are at rest and also to objects which are moving at a constant velocity. Two conditions for equilibrium are that the net force acting on the object is zero
