1. Observe. Label the points on the page where the collision appears to begin and end. Explain how you can tell. 2. Reason. Make a choice of coordinate system. Are you going to have it line up with the page, or line up with the initial velocity of puck A? Explain why. What units are you going to use for the velocities-cm/s or m/s? 3. Represent and Solve. Write an impulse-momentum equation for the x-direction. Isolate via (the equation will simplify). Make the necessary measurements from the next page (show these) and record your results in the chart. Solve for va 4. Represent and Solve. Write an impulse-momentum equation for the y-direction. Make the necessary measurements from the next page and record these in the chart. Solve for vi 5. Calculate and Test. Determine the vector V2. Carefully draw the vector beginning at the circle near the "B" (If you have the time, draw the circles too!) 6. Calculate and Reason. Use kinetic energy calculations to help explain what type of collision this is.
On this page is pictured part of a collision between two dry-ice pucks A and B (m, -m,- 300 g). The collision takes place using magnets and is captured using a strobe light that flashes 10 times a second. The centre of each puck is indicated using a small circle and the path of puck B has been erased. Puck B was initially at rest and was positioned at the small circle near the letter B. Show your measurements and velocity calculations on this page. 0 O Puck A, before (remember the uncertainties!)
