EXTRA OPPORTUNITY

In class on Wednesday, September 26th we determined that motion is relative and that motion in one dimension does not affect motion in another dimension. You may receive extra credit for creating some kind of video/movie that explains/demonstrates this concept. I am willing to leave this open for all kinds of interpretations but you must talk to me if you are interested in working on this either alone or with other people. Due by Friday October, 12th.

Fired and Dropped Bullet

If horizontal motion and vertical motion behave independent of each other a fired bullet and a dropped bullet should land at the same time if they are released from the same height simultaneously. Unfortunately, we don't have enough room in the lab to do this experiment. If only someone else could do it for us....

Feather drop on the Moon

If we had a bigger Science department budget (say $100 billion or so) we could have done this ourselves. I suppose we will just have to settle for the video.

Bugatti vs. Fighter Jet

Here is a 2 mile race between a Bugatti Veyron and a fighter jet. The car needs to travel a mile, turn around, and drive back to the start. The plane needs to take off, travel a mile straight up, then come back down to the start. Post your guess for the winner before you watch the video! The actual race starts around 6 minutes into the video.


Obviously, if the Quinngatti was in this race it would be a no-brainer, but I decided to stay out of it to make it competitive.

Usain Bolt's World Record Run

Usain Bolt holds the world record for the fastest time to complete a 100 m dash. He set this record in August of 2009. It appears that his fastest instantaneous velocity is 12.35 m/s (at 7.08 s). If applied to the formula v = ∆x / t this gives a time of 8.097 s, yet his record time was 9.58 s. For a bonus point added onto your homework this week post a comment explaining why these times do not match up.

Please note that this point will only be added to your assignment to make up for a missed point. You cannot earn a 16/15 on your homework. This comment thread may be used as a discussion, but only appropriate and constructive comments will earn points.
