This model is equations and spreadsheets only, and I no little about programming. Anyway, I need a genuine random number generator, not an periodic psuedorandom code-based number generator (One I was using seemed to repeatedly give me numbers over ^6, never below). I found one genuine random...

Hello. I'm currently making (or attempting to make...) a mathematical model based around mutation in a hypothetical organism (that is, one in which all the mutation rates and genome sizes are known). I am currently graphing a particular feature of this model, involving mutation rates, but I...

Solved it. Thanks a million for the help, I really appreciate it:D

To solve ½(-9.80)(t) + (vi)(t) = 7.5m vi = (16.9-9.8t) -4.9t + (16.9-9.8t)(t) = 7.5m quadratic equation 9.8t² + 12t – 7.5 = 0 {-b ± (square root)b² - 4ac} / 2a - 12 ± (square root) 144 – 4 (9.8)(-7.5) / 2(9.8) {12 ± 20.9}/19.6 1.6 or – 0.5 Vi = (16.9 – 9.8t) Vi = (16.9 – 9.8 (1.6))...

Thanks, I've redone the calculation and managed to get the Vfx and Vfy values correct. I've tried the d = Vit+½at² equation before, and got: 7.5m = (Vi)(t) - 4.9 (t)2. to find time I rejigged a = 0.5 (Vox + Vt)t to give t = a/0.5(Vox + Vx) 2t = (2)(-9.80)/(X + 16.9m/s) But...

Homework Statement To Find initial velocity, given final velocity, and displacement on Y axis. Hello. I've spent four hours trying different solutions to this following problem, none of which have worked. I've just started my undenominated science degree, and since I havn't started lectures...
