Document Content and Description Below

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 m2, with initial velocities v1i and v2i, and final velocities v1f and v . 2f 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 [Show More]
