Based on what info you gave I would use this: Vfs2 = Vis2 + 2asΔs Vfs2 = (1.6)2 + 2(-0.0067368421)(145) Vfs2 = 2.56 + -1.953684209 √(Vfs2) = √(0.606315791) Vfs = 0.7786628224 I got 0.7786628224 m/s, but you should check my maths :o Edit: oops too slow you went offline guess we'll never know ): |

That's ridiculous, I actually did this last night and it failed, I even redid it with the right acceleration too. (I technically can turn in the answer after 10, it just won't count.) |
