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).

Finally Guy confesses that he had a relationship with the woman and that

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

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

The phrase “turning point” has a lot of meanings but personally‚ for me‚ it is a moment that caused me to realize what has always been in front of me. Turning point may also mean a time at which a decisive change in a situation occurs‚ especially one with beneficial results. Recently‚ one event became the turning point of my life and my beliefs. Last Tuesday‚ our class‚ II-St. Therese watched the film “The Encounter”. That movie marked a pivotal moment in my life. It helped me realize that Jesus

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
