Hi, I just need some help with 3 questions that is asked in my rubric for this investigation. I have already done the experiment to investigate the relationship between the height from which a ball is dropped and the height of the resulting bounce 1. The problem statement, all variables and given/known data 1) Draw a graph of average bounce height versus drop height. These 3 questions I am unsure about 2) Should (0,0) be included as a co-ordinate? Explain. 3) Should the line pass through (0,0)? Explain. 4) How does the gradient of the graph compare to the ratio of bounce height to drop height 110 cm and 55 cm respectively. This is called extrapolation. Clearly show on the graph how you obtained these values. 2. Relevant equations 3. The attempt at a solution 1) Done, got a straight line graph 2) Unsure, I would say no because the ball cannot be dropped from 0 height 3) Unsure, I would also say no 4) My gradient worked out to be 0.49 and the ratio 55/110 gives me 0.5 so I would say they are the same. To show it on my graph I would just extend the line?
