Answer to Question 1

The greatest source of error is in determining the times to travel the various distances
because of the number of different students taking measurements and the human
errors made by each due to their reaction times in starting and stopping the clock.

Answer to Question 2

Yes, a ball thrown upward at its maximum height will have an instantaneous velocity
of zero but will still have an acceleration (due to gravity) of 980 cm s2 .
