mass m initially at speed u collides head-on (without rotation) with a stationary puck of mass M. Find the velocities of both puck after the collision if: i) the collision is fully elastic ii) the collision if fully inelastic. i) momentum: kinetic energy: mu = mv+MV (+ve in direction of initial u) 1 /2 m u2 = 1/2 m v2 + 1/2 M V2 2 eqns in 2 unknowns: V = (u - v) m/M substitute in K eqn: u2 = v2 + (M/m) V2 = v2 + (M/m) (u - v)2 (m/M)2 = v2 + (u - v)2 (m/M) let ρ = (m/M) ⇒ v2 (1 + ρ) - 2ρ u v + u2

and Field event that uses various energy systems and muscles. The three energy systems used within all sports include: • ATP – PC System (Anaerobic System): This system works by breaking down food energies (stored in the cells) to produce energy and Adenosine Diphosphate (ADP). From here Phosphate Creatine (found in muscles)‚ a chemical compound‚ combines with ADP to produce more ATP. This system is used best for high intense events using large bursts of energy. • Lactic Acid System (Anaerobic

affected by thermal energy? My answer to that question is when thermal energy is added to the substance‚ the particles have increased on energy and move around more‚ but when thermal energy is decreased‚ particles are closer together‚ so they don’t move as much because they are low in energy as well as space. Temperature: The question being asked to answer is if temperature is affected by thermal energy. My answer to that question is its affected because when you add thermal energy the temperature

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

Energy resources have had a widespread effect on everyday lives across the nation. Day by day from sunup to sundown about 30 percent of the world’s energy is being used by the United States. Ideally energy comes from the burning of fossil fuels and oils imported from across the globe. However‚ there has been various disputes on how the United States could find alternative energy sources for widespread use. Alternative energy is any form of energy used that is not fossil fuel that come from energy
