Part 3: The following speed versus time graph is for a toy rocket shot straight up in the air. Note that the moment that the toy rocket leaves its launch pad, it has all the kinetic energy that it ever has. As the toy rocket moves upward it slows down until the moment in time that it has gone as high as it can. At this moment it has no Kinetic Energy and pauses, and then starts falling straight back down to the Earth. (I have put the graphs from Part 1 and Part 2 together to cover the entire time period of the toy rocket going up, pausing at its maximum height, and falling straight down.) Speed SEC 0.04 0.9 20 40 6.0 80 10 0 12.0 Compare the speed of the toy rocket at 3 seconds to its speed at 9 seconds. Which is greater? By how much do they differ? Remember that at 3 seconds the toy rocket is going straight up 7 11
