4. Considering delta notation, determine the general meaning of the slope of the position -time graph.5. What is the numerical value for the rate of change of separation displacement?6. What can you say about how the separation displacement is changing?7. Considering the initial velocities of each object, could the rate of change of separationdisplacement be determined indirectly (without measurement from motion maps)?V c = _________V r = _________8. Now suppose that the same two ships are again travelling on the same path, but inopposite directions, with the same speeds as they had before. Imagine you are on the“rectangle” ship but this time the “circle” ship is ahead of you and heading towardsyou. How would you determine the relative velocity of the circular ship?Part 2:Two Dimensional Relative VelocitySituation: We will now use Working Models to examine the situation where twomoving objects, such as our two ships, are travelling in a straight line but notalong the same path.→ Open Working Models by clicking on the minimized Working Models window (located nextto the start button).→ Since we are entering back into the previous simulation the environment set-up willbe the same and we will only need to change the property settings of each object.- 23 -
