= 300g 9.8 3. Explain the effect of mass on Hooke’s Law. Hooke’s Law states that the restoring force of a spring is directly proportional to a small displacement. Applying a mass to the end of the spring stretches it‚ changing the length from its original equilibrium position of rest‚ to a new (lower) equilibrium position. At this position‚ the vertical restoring force of the spring balances the weight and the downward pull of gravity is balanced by the upward pull of the spring

A ball is thrown upward at time t=0 from the ground with an initial velocity of 18 m/s (~ 40 mph). Assume that g = 10 m/s2. Time to reach apex 18/10 = 1.8 Time x 2 = 3.6 Great height reached by ball – (Velocity)(time)+(-5)(time^2) 18x1.8+(-5)(1.8^2)=16.2 A model rocket accelerates upward from the ground with a constant acceleration‚ reaching a height of 63 m in 8 s. * Speed at height 63 - 2x63/8 = answer What is the acceleration= answer/8 * If you were to drop a rock from a tall building

Types of Forces Used in Basketball Forces are found everywhere‚ but of course‚ you can`t see them. They act on you for example if you are waking there are many forces that act`s on you. If they are not involved you can`t wake. Let`s talk about the forces that are involved in basketball. Basketball is a very enthusiastic sport and you must try it‚ you are not going to regrets. Basketball has original thirteen rules‚ but I am just going to mention 10 of them. 1- The ball can be thrown in any direction

Five Forces Analysis What is it? Five Forces Analysis is a tool that enables managers to study the key factors in an industry environment that shape that nature of competition: (1) rivalry among current competitors‚ (2) threat of new entrants‚ (3) substitutes and complements‚ (4) power of suppliers‚ and (5) power of buyers. When do we use it? In a strategic analysis‚ Five Forces Analysis is an excellent method to help you analyze how competitive forces shape an industry in order to adapt or

getting ahead and keeping that position can become very difficult. The fact is that both Microsoft and Apple have been plagued with missed opportunities over the years even though both have some of the strongest brands in the world. Now‚ the reason why Microsoft has dominated the market is quit simple. Besides the fact that both companies have very different core products and working culture‚ Microsoft is the world’s biggest and richest company‚ run by the world’s richest man‚ who succeeded

to government officials and the use of their power and force. These areas can easily be misconstrued and misunderstood. Police officers are put in situations where they are sanctioned to use mental and physical force to catch criminals with the goal of solving a crime. (p481). When it comes to police force‚ some have a good understanding of its purpose and feel that it is needed. Others believe that with training and self-control‚ police force could be minimized. We live in a society that is unpredictable

How competitive forces shape strategy Pflicht 4. (5Forces) " 1 von 3 While one some- times hears executives complaining to the contrary‚ intense competition in an industry is neither coincidence nor bad luck. Moreover‚ in the fight for market share‚ competition is not manifested only in the other players. Rather‚ competition in an industry is rooted in its underlying economics‚ and competitive forces exist that go well beyond the established combatants in a particular industry. Customers
