questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

While Bolger’s analysis looked broadly at police use of force‚ the analysis by Harris looked only at improper use of force. What is the difference between these two concepts and what differences did you notice regarding Bolger’s results and Harris’s findings? The obvious difference between the study of the use of force and the study of improper force is easily understandable. Bolger looked at a broad sense and didn’t leave out the use of force in a rightful manner which in my opinion led to different

In the past 30 years‚ Porter’s five forces model has been recognized as one of the most useful strategic management tools which can be used to analysis organization external environment‚ so as to help organization build up competitive advantages. However‚ with the development of the world‚ the five forces model has been challenged that it cannot be continued use to adapt today’s dynamic environment. This essay aims to challenge Porter’s five forces model and to identify the problems which hide behind

CEMB 121 MECHANICS OF MATERIALS LABORATORY EXPERIMENT (NO.2 (a)) SHEAR FORCE I SUMMARY Shear Forces occurs when two parallel forces act out of alignment with each other. For example‚ in a large boiler made from the sections of sheet metal plate riveted together‚ there is an equal and opposite force exerted on the rivets‚ owing to the expansion and contraction of the plates. The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of

The Use of Force The Wichita Police Department’s policy and procedures on the use of force for its employees takes every measure of precautionary to ensure that the best method of force is used in making a lawful arrest. These policies and procedures go into great detail to inform officers when the use of force is necessary and how much force is needed. An officer of the WPD is justified in using force as long as they believe it to be necessary to effect the arrest and to defend one’s self or another

Kamal uddin At‚po—pokhraira‚ via Birouli(R.I)‚samastipur(Bihar)‚ India ABSTRACT It is well established that the forces between nucleons are transmitted by meson. The quantitative explanation of nuclear forces in terms of meson theory was extremely tentative & in complete but this theory supplies a valuable point of view . it is fairly certain now

Universal Gravitation Apples had a significant contribution to the discovery of gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other mass. This is the

[pic] The product of average force and the time it is exerted is called the impulse of force. From Newton’s second law [pic] the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: |[pic] |Calculation | The main utility of the concept is in the study of the average impact force during collisions. For collisions‚ the mass and change in velocity are often

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre
