Phys 151L/170L – Physics I Laboratory Experiment: Conservation of Energy and Momentum in a Collision Due date: Friday 10/23/20 (submission on Laulima as pdf) /58 total points Instructions: Pleas e adhere to the guidelines in the syllabus to prepare your solution. You must show all calculations clearly. If you don't, you will not receive credit. Theory ​(7pts total, 1pt each) 1) What does it mean for the collision to be elastic? A collision system with no net loss in kinetic energy. 2) Write the equation that describes momentum conservation in a collision for two carts of mass ​m​1 ​and ​m​2​, with initial velocities ​v​1​i ​and ​v​2​i​, and final velocities ​v​1​f ​and ​v ​. ​2​f pi = m1v1i + m2v2i = m1v1i + m2v2f = pf 3) Write the corresponding equation for kinetic energy conservation. T m v m v m v m v i = 21 1 1i2 + 21 2 2i2 = 21 1 1i2 + 21 2 2f 2 = T f 4) What is the equation of ​v ​in terms of ​s ​and ​t ​? v = st 5) What equation do we use to calculate the Transfer of Energy (TE) ratio in the experiment? 6) What are the units of the TE ratio? T E = No units. E 1i E2f 7) What function do we use to find the theoretical TE value? (Hint: function is independent of velocity) Note: your answer will not be the same as question 5
