projectile motion
Projectile Motion
  • Projectile motion- The path an object travels through space.
  • I am Proving that Jack will not be able to make it clear across the cliff by launching himself into the air with the stick tied to him.
movie explanation
Movie Explanation
  • Captain Jack gets tied to a bamboo stick and he gets hunted and gets fruit thrown at him which ironically gets stuck to each end of the stick. He tires to escape by  a catapulting launch with the top of the stick across the cliff.
estimates
Estimates
  •  Stick length- .09 m 
  • Mass weight- 185 lbs
  • Time- 3.80 seconds
  • Distance- .34 m
  • Starting angle-40°
calculations
Calculations
  • D=Vxt
  • 34m = Vx(3.8)                Vx = VicosΘ
  • 34m/3.8                            8.95m/s = Vi (cos40°)
  • Vx = 8.95 m/s          Vi = 11.68 m/s (3600s)(  1min  )
  • hr      1609m
  •                                                        Vi = 26 mph
  •  Explanations:
  •    I first took the first equation which was distance =  velocity x time which gave me the distance that he was running. The second equation I  simply plugged in the distance to the equation to find the speed that he was running and after multiplying anf dividing out the numbers that were found I got that Jack was running 26mph.
formulas
Formulas
  • D=Vxt
  • Vx=Vi cos Θ
  • H=1/2 gt 2
what should have happened
What should have happened.....

Vx= 8.95m/s

*If he was running at 8.95m/s he would be going down when running off the cliff. He would drop a total of 47m, which is halfway down the cliff from where he originally landed.*

comparison
Comparison
  • Top speed of an olympic sprinter- 2.31 m/s
  • He was running  11.68 m/s
  • He is going 5 times the speed of an olympic sprinter.
  • In the calculations I found Jacks speed which was 26mph. After plugging the olympic runners speed in we got 5.17mph. That wouldd prove that Jack is running 5 times the speed of an olympic runner.
  •    **** Vx = VicosΘ**** 
  • 2.31m/s = (3600)(   1   )    Vx = 5.17 mph  
  • hr      1609                                 
conclusion
Conclusion
  • In conclusion Captain Jack will not be able to make it clear across the cliff because he will come too short of the other edge.
