Mission Possible 3

Mission Impossible 3

Agent Ethan Hunt (Tom Cruise) swinging from one building to another in Shanghai -
Could he make the jump? To find out we would need to know:
Building 1 height: 226 meters (Where he jumps)
Building 2 height: 162 meters (Lab)
X distance: 47.5 meters
Initial velocity x: -25 mph (-11.2 m/s)
Final velocity x: 15 m/s
Initial Velocity y: 0 m/s
Final velocity y: 10 m/s
Acceleration X: 0 m/s^2
Acceleration Y: -9.8 m/s^2
Time~ 18 seconds
To get the initial x velocity, I used the average human speed and took that because he runs backwards off the building.  To find the time I counted and subtracted 2 seconds for the slow motion time.  The heights were given in the movie and the x distance was too.

Drone Attack Scene
Ethan jumps a hole in the bridge.  Could he make the jump?
Hole width: 4 meters
Time: 1 second
Initial velocity: 5 m/s
Final velocity: 5 m/s
To get the holes width I used the car next to it as a guide.  The initial velocity was guessed because he started to run.  He never got to full speed so I took half of the average human velocity for his initial velocity.

Vatican City wall
Ethan repels off of the Vatican City wall.  My question is would he be able to stop that quickly and not hit his face on the ground and would it have needed more time for him to reach the ground or less time.
Y distance: 16.55 meters
Y acceleration: -9.8 m/s^2
Y final velocity: -29.4 m/s
Time: 3 seconds

  1. I'd like to see you write your blog entries so that they are readable and understandable by pretty much anyone. The way you wrote it only makes sense if someone read the assignment on my blog before looking at yours. On the building swing in Shanghai, it's not clear to me how you got the final velocities you quote. That's an important component of the assignment. For the bridge jump scene, why do we need to know the time? Is there anything else we might need to know? For instance, does it matter what angle he takes off at? For your last scene, you didn't even bother explaining how you got any of your estimated quantities, nor did you discuss why you think they are important.
