The problem:
Answer the following:
• How accurately do you think you can measure the time between two events using the TIMER program?
I think I could accurately measure the time between 2 events within .5 seconds.
answer/question/discussion:
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
The shortest time interval measured would probably be around .3 seconds.
answer/question/discussion:
• How does the percent error in timing intervals change as the time between the events gets smaller?
The error percent would increase because it would be harder to measure.
answer/question/discussion:
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
Within .5 seconds.
Position is not measured in seconds. In what units is position measured on this video, and how accurately do you believe you can measure it?
answer/question/discussion:
** **
20 minutes

If you can only measure position accurately to within .5 seconds, how would it be possible to measure and interval lasting only .3 seconds?
&&&Was I suppose to look at a Timer program to get my calculations or was I suppose to estimate what I think I can do?

The initial Timer exercise preceded this question so your answer should have been informed by your experience with the Timer.
I think you can measure time intervals more accurately than you estimate, probably about twice as accurately, but there is nothing seriously wrong with your estimate of 'within .5 seconds'. However if you can measure only to within .5 seconds, then you cannot measure something as short as .3 seconds.
