A jump of Stelios cutting of the Persian Emissaries Arm

300 Movie

Physics PropertyThe jump is not possible with the

short running distance.

Also he only jumped off one leg.

Spartan Jump

Calculations

•Height of Spartan = 6ft/6cm on screen•Measured Triangle on screen Horizontal =12ft./3.6576m Vertical = 2.5ft/.762m Diagonal = 12.5ft/3.81m

CalculationsTriangle:(12ft x .3048m) / 1 ft = 3.6576 m horizontal distance(2.5ft x .3048m) / 1 ft = .762 m vertical distance(12.5ft x .3048m) / 1 ft = 3.81 m hypotenuse Times 2 = Arc distance = 7.62mTime: 1 /3 Video Time(3.6234s + 3.6036s + 3.7554s) / 3 = 3.66 s Average Time in airVelocity:Vertical d=ViT+1/2gT2 .762 = Vi(3.66) = 1/2 (-9.81)(3.66)2 Vi= 18.159 m/s Horizontal V=d/T V=3.6756 / 3.66 = .999 or 1 m/sDiagonal Velocity a2+b2=c2 c2 = 330.87 c=18.19m/s

World Record Long Jump

CalculationsWorld Record Long Jump = 8.95mAverage Time In Air = (.97s+1.04s+1.11s+.97s) / 3 = 1.0225sVertical VelocityD = ViT + ½gT2

8.95 = Vi(1.0225s) + ½(-9.81)(1.0025)2 Vi = 13.77mHorizontal VelocityV = D/T V = 6.347/1.0025s V=6.207m/sHypotenusea2+b2=c2 c2 =115.09 c=10.73m/s

ConclusionSpartan jumps 7.62m in 7.32sLong Jumper jumps 9.85m in 1.0225sSpartan takes 2 StepsLong Jumper: Full out sprintSpartan: Crazy Hang timeSpartan Travels Through air at 40.69 mph
