### acceleration01.iwp

Play the animation to view an object moving horizontally across the screen. Its acceleration is uniform. Step through the animation and take measurements of x-position and time to use for finding the acceleration. The object enters the field of view at -10.0 m and leaves (momentarily) at +10.0 m. Tic marks are placed every meter. Read positions of one side of the object to the nearest 0.1 m.

The graph shows position vs. time of two objects which we will call a hare (red) and a tortoise (blue). The animals are in a race.

The initial positions and velocities of the animals are given. These can be changed to produce different results. After changing any input, click Reset. Time, position, and separation of the animals are given above the play buttons.

Change the acceleration to 0.5 m/s**2, reset, and run again. Click Show graph. The black line shows the distance between the hare and tortoise as a function of time. Note how it dips to a minimum and then rises without ever reaching zero. What is the greatest acceleration that the tortoise can have and still be caught by the hare? Where and when do their paths intersect?
