I. A child rolls a marble on a track that is 100 cm long as shown. 100 can Use x to represent the position of the marble along the track. The child gives the marble an initial speed at x = 0 m and t = 0 s and 20 cm then watches it roll to x = 100 cm, where it turns around, and returns to x = 0 m with the same speed with which the child pushed it. On the coordinate axes below, plot the position, 10 cm 60 cm velocity and acceleration of the marble as a function of time. Note: On the coordinate axes, too . is the time at which the marble is at x = 20 cm, to is the time the marble is at x = 40 cm, etc. Since the marble turns around, there are two top . one for the first time it reaches that position, and one for the time on its way back. Hint: Plot the v vs. t first and use the plot to figure out the other graphs 20cm tau em $50 cm find cm them tablem tzucm tocm $100 cm 60cm taocm 20cm tom tam cm tadcm $60cm 108 cm tedem tadem tzdem form
