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? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total

ENERGY CONSRVATION : A VIEW FOR ENERGY MANAGEMENT & ENVIORNMENT BY:-Harshal rane (BE MECHANICAL) ABSTRACT :- In present world the need for electrical energy is quite essential in every aspect of our life‚ but at the same time the crisis for the electrical energy has been increasing proportionately. The present trend of producing electrical energy via coal‚ nuclear and hydro means are degrading the healthy atmospheric conditions an they are also in

KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy is

Physics Energy Exploration Project Energy can be stored in many forms as potential energy. It can be extracted through chemical and mechanical processes to get usable energy. We use that kinetic energy and electricity every day to power our lights‚ run our cars and do most of our tasks. Fossil Fuel is a non-renewable energy source. It results from the decomposition of dead and buried organisms. They are millions of years old and are fossilized under rock and sand. They are efficient energy producers

Cayla Wierenga Ms. Pintek Health 9 April 2013 Muscle Growth DR. PAUL D. THOMPSON‚ a 60 year old marathon runner and chief of cardiology at Hartford Hospital‚ stood in front of a medical audience recently and began his talk with a story about himself. Hes had been lifting weights since he was 12 years old. Dr. Thompson is now a small and wiry with not a bulging muscle on him. He was speculated that he must have a genetic inability to build muscles‚ no matter how hard he works at it. But

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate

Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal
