thanks that will be great

Calculating effects of air resistance on a ball of mass 0.67kg, being dropped from a height of 4.93m. I have worked out theoretically what time it would take without air resistance using s=ut + 0.5at(squared) however i cannot find an equation that will factor in air resistance. thanks

yeah its nice to just join in with random comments every now and then it was gd crack last night x

fair enough gd stuff will speech on sunday then =]

ahh ok thanx, can i ask why?

Is the physics chat just open certain days or what?

9.03x10^15 x

oops that should have been 10^23 lol, thanks i'll try that x

A scientist wishes to find the age of a sample of rock. Realising that it contains radioactive potassium, which decays to give a stable form of argon, the scientist started by making the following measurments: decay rate of the potassium in the sample = 0.16Bq mass of potassium in the sample...

But at the same time something must help us make our desicsions, possibly the chemicals in our body and if that's the case, our chemicals don't change therefore our choices are already made.

yeah, basically do you believe that our path in life is already chosen.

I am writing an essay on determinism, i was just wondering what peoples opinions on it are, my argument is going to be that it is possible, but i would like to include other peoples opinions and reasons. Thanks Steph.
