5. a) Given the following initial conditions Elasticity 60% Elastic Mass (kg) Position (m) Velocity (m/s) Momentum (kg m/s) 1 2.00 -1.03 -0.36 1.26 0.49 2.52 0.98 2 2.50 1.51 -0.34 Solve for the initial velocity components of mz (show your work) that will produce the following final velocities: [4] Mass (kg) Position (m) Velocity (m/s) Momentum (kg m/s) Px Py 1 2.00 0.01 1.53 -0.22 1.06 -0.43 2.11 2 2.50 1.36 -0.22 0.46 -0.15 1.15 -0.38 b) Check your answer from 5a) in the simulation (use the given initial position values). Hint: other than your calculated initial velocity components for m2, everything else (including position) must be entered exactly as shown for the initial conditions. In order to set the negative values for the initial y positions, you may need to drag the balls to the bottom of the screen and then adjust the numbers in the data chart. Part 4: Application Questions 1. For what conditions is momentum conserved in a collision? Provide a real-life example of such a collision. [2] 2. Provide a real-life example of a collision in which momentum is not conserved. [1] 3. Compare and contrast elastic vs. inelastic collisions. ( How are they similar? How are they different?) [2]
