Group Members: Trevor, Kendall, Antonika Goal: To test the plausability of an action stunt from a movie.

Procedure: 1. Find movie clip (from //True Lies//) 2. Research brand/model, of motorcycle used to find its acceleration rate, and mass 3. Estimate the distance on the roof the bike travels, and the distance between the two buildings 4. Calculate distance of fall given the horizantal distance hypothetically traveled

Data: Motorcycle: **Kawasaki Ninja 500** Mass: 169 kg Acceleration: 0-60mph in 3.76 sec Length: 6.975ft = 2.126m Actor: Grant Heslov Height: 5'9" Weight: 155 lbs = 70.307kg Average Width of Traffic Lane: 12 ft = 3.658m Sidewalk Width: 10ft = 3.048m Marriot ledge: 10ft = 3.048m Ledge to Mid-pool Distance: 15ft = 4.572m Height of Westin Bonaventure Hotel in Los Angeles: 112m Building across street: 76m Accelerated for: 4.2 seconds Vf: 67.021 mph = **29.961 m/s** Total Distance Traveled (Horizontally): **24.69m** Total Distance Traveled (Vertically): **76m**

Calculations: -36 = 0*0+.5*-9.81*t^2 t = 2.709 seconds 30*2.709 = 81.27m

Conclusion: The vallainous terrorist antagonist that narrowly escaped Arnie on horseback via motorcycle from the roof of the building into the roof pool across the street could actually potentially achieve this feat based on our calculations. The motorcycle being driven in this scene was a Kawasaki Ninja 500 which has an accleration rate of 0-60 mph in 3.76 seconds, and we measured the time between when the motorcycle was at rest and when it became a projectile, which came out to be 4.2 seconds, giving the motorcycle a Vf of 29.961 m/s. We estimated the difference in height between the two buildings to be roughly 36m, and the distance between the spot where the villain became a projectile and the middle of the pool across the street to be 24.69m. Using the formula above we used the vertical change in distance to determine how long the villain would be able to be in the air before reaching the height of the second building, and multiplied that value with the Vf of the motorcycle to determine the motorcycle could have potentially fallen 36m and moved 81.27m horizontally at 29.961 m/s. Since projectiles never change their horizontal velocity (discounting wind resistance) the difference between the height of the buildings allowed time for the driver covered the desired distance before the impulse was cushioned and distributed by the pool water. We were very surprised of the potential distance he could have traveled (=0), we were expecting that what occured in the film would have proven to be an impossibility in the physical world, but he actually could have overshot the pool fairly easily. Yay.
