I'm just a high school physics student, and this is my first physics class. Anyways, I was watching Mythbusters a few days ago and saw the myth that a car could turn 90 degrees @ high speeds if a grappling hook was shot out at a structure at the corner of a turn (see diagram below). I've never dealt with centripetal forces before and was just wondering how you would create a force diagram for an object with centripetal forces.

Here's my take on it, but I'm just blindly guessing here:

Note that the car is already caught in the circular motion when position 2 is drawn. Also, forgive my messy handwriting and drawings :)
