I'm more interested in how you measure total force in Jellos. [/ QUOTE ] |

Okay, my post has seemingly resulted in mass confusion, so I'll work through my answer.
Force is mass times acceleration, so if you know the acceleration the Jello imparts on the dog, you get force. First, I determined the speed the dog was traveling at when it reached the Jello: Vf^2 = Vi^2 + 2ad a = 10 (I kept it simple) Vi = 0 d = 20 Vf^2 = 400 so Vf = 20. I used the same equation to determine the acceleration of the dog in Jello: Vf^2 = Vi^2 + 2ad Vf = 0 Vi = 20 d = 10 0 = 400 + 20a Therefore, a = -20 m/s. Then, it's just the force equation: F = ma m = 20 a = 20 F = 400 |
