I was able to watch Mission Impossible 3 for the first time recently. Overall I thought the movie was action packed and enjoyable. However, I will be analyzing three scenes from the movie to determine if the physics were realistic or not.

The first scene I will be discussing is the scene where Ethan throws a gun to the woman he is rescuing more towards the beginning of the movie. In order to figure out whether the throw would be as simple as Ethan (Tom Cruise) made it seem you would first calculate the time it took for the gun to travel from Ethan's hand to the woman. Now, one can either calculate the exact time or make a logical estimate. The estimate I've come up wit is 1.5s after watching the scene. Next one would need to find the displacement. One could figure that out by figuring out the length of the gun used and how long Ethan's hand travelled. An estimate for the gun could be 217mm and for Ethan's hand you could estimate 26, then once you multiply the two numbers together you get 5642mm. Once you convert to meters you get 5.642m. Lastly you need to calculate the time it took. For that you would simple you would just calculate the displacement and the time together. Once you get your result you learn that the scene was in fact possible. Especially for a special agent.

The next scene is when Ethan swings from one building to the next. First you would need to find out the height of each building, once you get the heights, which according to the movie where...
building one: 226 meters, building two: 162 meters and the distance between them was 47.55 meters. The initial velocity was 9.8m/s consider he free falls from the building. You would also be able to figure out the time it took him to fall off the building until the rope reach its capacity. with that you get about 20 seconds. Now that we have found all this information you are able to calculate whether or not the scene would be possible.


The last scene I want to discuss is the scene when Ethan jumps over an opening in the bridge. Ethan is played by Tom Cruise. Tom Cruise is around five seven. By the looks of the scene the opening seemed to be about roughly 4x of Ethan's height. Therefore given how fast Ethan was running and the force he would have to give in his legs, I thin the scene was somewhat accurate. Considering he did not fully make the jump.

  1. OK, not bad. You’re using mostly the correct physics terms and thinking about some useful quantities to estimate. There are some mistakes, though, in your applications of physics to the different scenes. But that’s the point of the course; hopefully, you’ll be able to do even better by the end of the semester.
