Part 1: 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 the highest speed and, therefore, 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. Speed 0.0. sec 0.0 20 40 60 60 100 120 Compare the speed of the toy rocket at 2 seconds to its speed at 5 seconds. Which is greater? By how much do they differ? By knowing that the rocket is going straight up in the air, compare the height above the ground of the toy rocket at 2 seconds to its height above ground at 5
