### Hot rod jump - andrew

1. 1. Hot Rod Jump By: Andrew Cheung Physics 10 Ms. Symes
2. 3. Aim <ul><li>The aim of this presentation, is to find out, whether or not this jump is real, or just movie effects. </li></ul>
3. 4. Hypothesis <ul><li>My origional hypothesis, was that this jump is possible, if the ramp was reinforced and stable. </li></ul>
4. 5. Materials <ul><li>Video </li></ul><ul><li>microsoft paint or adobe photoshop </li></ul><ul><li>Google images </li></ul>
5. 6. Information gathered <ul><li>The average width mail truck is 1.80 meters </li></ul><ul><li>2cm= 180 cm </li></ul><ul><li>1cm= 90 cm </li></ul><ul><li>4.5 cm x 90= 810 cm = 4.05 meters(jump distance) </li></ul><ul><li>10cm x 90= 900 cm =9 meters (distance traveled)  </li></ul><ul><li>9 meters traveled in 2 seconds </li></ul><ul><li>the ramp is at 15 degrees. </li></ul>
6. 8. Legend <ul><li>r is distance </li></ul><ul><li>v is the final velocity </li></ul><ul><li>sin is angle </li></ul><ul><li>this is all over gravity, which is 9.8 meters per second </li></ul>
7. 9. Working <ul><li>R = V ^ 2 Sin 2  ∠ </li></ul><ul><li>                   g </li></ul><ul><li>4.05        V ^ 2 Sin (15) </li></ul><ul><li>____  =  _________ </li></ul><ul><li>    1               9.8 </li></ul><ul><li>39.69         V ^ 2 Sin (30) </li></ul><ul><li>_____   =   __________ </li></ul><ul><li>  0.5                 0.5 </li></ul>Cross Multiply   Do math
8. 10. Workings part 2 <ul><li>39.69         V ^ 2 (0.5) </li></ul><ul><li>____    =    _______ </li></ul><ul><li>0.5                 0.5 </li></ul><ul><li>79.38 = V ^ 2 </li></ul><ul><li>8.9 </li></ul>Divide  (0.5 cancel out) Square root  Equals minimum speed needed
9. 11. Conclusion, Was the jump possible?  <ul><li>The answer is no.  </li></ul><ul><li>The jump in this movie, was a failure as &quot;Rodney Kimble&quot; was unable jump the mail truck, as the ramp broke. Even if the ramp were reinforced, he would have similar results to the movies, because he traveled at 4.5 meters per second.  </li></ul><ul><li>The minimum speed needed, was 8.9 meters per second, in order to jump the 1.80 meter truck. </li></ul><ul><li>This resulted in serious injuries. </li></ul>
