Collisions Lab Section (Day & Time): Name: Date: Pre - laboratory Assignment Duc at the beginning of your lab class. Answer all questions. Only some will be graded, for a total of 10 points. 1. In this experiment, what should you not touch? 2. In this experiment you will study the effect of collisions on a system consisting of 3. What will be the time interval between two adjacent dots on your spark trace? 4. The drawing to the right shows a collision between two pucks on an air- A hockey table. Puck A has a mass of 2.8 kg and is moving along the x axis with a velocity of +5.5 m/s. It makes a collision with puck B, which has a mass of 6.3 kg and is initially at rest. After the collision, the two pucks fly apart with the 65 angles shown in the drawing. +5.5 m/s A 4a.
