- 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.

- 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.

- Stick length- .09 m
- Mass weight- 185 lbs
- Time- 3.80 seconds
- Distance- .34 m
- Starting angle-40°

- 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.

- D=Vxt
- Vx=Vi cos Θ
- H=1/2 gt 2

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.*

- 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

- 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.
