Answer the following questions using the data collected in the collision tables from question one a. Is momentum conserved in each collision? /1 b. Is kinetic energy conserved in each collision? 43. Using the data in the table below and the percent loss formula below % loss = Initial energy-final energy x 100% initial energy a) Determine the percentage of kinetic energy lost for each collision. (2 marks) /2 Collision Elasticity Initial Final Per cent loss kinetic kinetic energy (J) energy (J) in kinetic energy 1 100% 90 90 2 76% 90 68 3 54% 90 49 20% 90 18 b) The Law of Conservation of Energy states energy is neither created nor destroyed. /1 Explain what happens to the energy lost in the table above. (1 mark) /2 4. Describe the mathematical relationship between elasticity and the percent loss in kinetic energy. Compare two data points from the above table in your reasoning.5. A ballistic pendulum experiment is shown in the diagrams below. The ball has a mass of 0.200 kg and the wooden block has a mass of 1.000 kg. Use the data in the diagrams to do appropriate calculations to determine if the collision is elastic or inelastic. The values in cm represent the height each object is lifted to. Before: . Ball pendulum is released, striking block pendulum After: Ball pendulum rebounds . Block pendulum responds to impact 1.50 cm 0.10 cm /56. A new communications satellite launches into space. The rocket carrying the satellite has a mass of 2.04 x 10 kg. The engines expel 3.7 x 103 kg of exhaust gas during the first second of liftoff giving the rocket a velocity of 5.7 m/s [up]. At what velocity is the exhaust gas leaving the rocket engines? Ignore the change is mass due to the fuel being consumed. The exhaust gas needed to counteract the force of gravity is already been accounted for and should not be part of this calculation. Show all calculations
