Assignment – Physics 1 1. Two carts‚ one twice the mass of the other‚ experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact

found out that all that force applied exert about 1600 pounds of force to his arms. Not even the worlds strongest man can lift that much!! Next we talk about spider-man and his trickery. In his the movie spider-man 3 is basically immortal‚ never dying person. For example In a climatic battle scene spider man fall 80 stories and survives without breaking a bone‚ concussion‚ or presumably any internal bleeding. Lets use Newton’s second law to calculate (Fnet=ma) how much force the ground exerts on spider-man

it is close to Earth then it is around 8km/s. 17. Why is it important that such a satellite be above Earth’s atmosphere? It is important because it avoids the heating effects of atmospheric friction. 18. What force acts on a satellite that is above Earth’s atmosphere? The only force is gravity. Plug and Chug 1-5 1. Calculate the resultant velocity of an airplane that normally flies at 200 km/h if it encounters a 50 km/h tailwind. If it encounters a 50 km/h headwind? 200+50=250km/h 200-50=150km/h

Intermolecular forces exist between independent particles‚ such as atoms‚ ions‚ or molecules. They can be forces of either attraction or repulsion. The amount of charge‚ how it is distributed‚ and the length of time that a charge distribution exists can affect the strength of intermolecular forces. And despite having variable force strengths‚ all intermolecular forces are considered weak compared to chemical bonds‚ or intramolecular forces. Chemical bonds are not only stronger; they are also more

Intermolecular Forces Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms‚ molecules or ions). They are weak compared to the intramolecular forces‚ the forces which keep a molecule together. There are a few types of attractive intermolecular forces such as: Dipole-Dipole Forces Dipole–dipole interactions are electrostatic interactions of permanent dipoles in molecules. These interactions tend to align the molecules to increase the attraction

Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

Competitive Forces (Porter’s 5 Forces) Analysis of the competitive environment can be done utilising Michael Porter’s 5-forces model of UPS and FedEx. Porter’s theoretical framework allows us to determine the overall profitability and sustainability within the industry (Laudon & Laudon 2006‚ pg.99; Hubbard 2004‚ pg.211). We reckon that in this case‚ the competitive forces for both UPS and FedEx are very similar because they are both in the same industry. Power of substitutes: Communications

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

As Porter’s “Five Forces” model describes how certain areas of the industry could be affected or affecting the entire game‚ and people throughout the basketball world. The way that I look at this situation and in regards to the N.B.A. and the players‚ because of a strong competitive force in the industry‚ and according to Porter‚ these forces can be a threat on the entire involvement in basketball.
