The+Good,+The+Bad,+and+The+Ugly

**Knight Rider Ramp good physics:**media type="youtube" key="dYlstdCWzCY?fs=1" height="385" width="640" align="right"
In the popular show "Knight Rider" the driver is able to drive his car into the trailer while both cars are moving. Using Newton's first law, he is able to drive straight into the trailer as long as he only accelerate enough to get in.

**Gone in 60 Seconds bad physics: media type="youtube" key="8Y_hcQQXxt8?fs=1" height="370" width="647" align="right"**
There is no way that Mustang could make that jump. The Mustang was traveling at a speed of 120 mph or 54 m/s and he went up a ramp at 45 degrees. It took him about 5 seconds for him to come down. Just using the x factors he could not have made it. He would have only gone 191 meters. In the video it shows the car jumping about half the bridge. The bridge the director used was the Vincent Thomas bridge which spans 460 meters. Divide that in half and the car had to make it over 230 meters and it clearly didn't. The doesn't follow a parabolic path. The car stays at the same height and then suddenly falls. Even if he could land the jump, his car would probably not be able to drive away perfectly. This was done by CGI.

**Assassin's Creed Leap of Faith ugly physics:** media type="youtube" key="lYZpOYra6Wc?fs=1" height="385" width="640" align="right"
In the popular video game series Assassin's Creed, the main character is able to climb to the top of the building in the cities and scan them. After he scans the city he takes a leap of faith. The assassin jumps and falls into a convenient stack of hay. In the real world he would not be able to just walk away after the fall.

The average man has a mass of 70 kg. The tallest building in the game is Giotto's Campanile which is 84.7m tall. Using Vf^2=Vi^2 +2ad I found that the assassin will hit the ground at 40.7m/s. He will be falling at the rate of g or 9.8m/s/s. So when strikes the ground he will feel 686 N which will probably injure him in some way. There is also the hay which will not do much to help the assassin. The hay would have to reduce his acceleration to a reasonable number for him to survive. This is ugly physics.
