Walterke, please explane what is wrong that equation.
I appreciate the advice, the rock is falling on a solid surface, the significance of the answer I am after is very minor, a best geuss would do to be honest but I did want something a little better than that
Thanks for the replys guys, quick question can I just do this to get a rough answer?
v^2 = 2*g*h = 7m/s
KE= 1/2*m*v2 = 784j
Force at impact = KE/distance = 318N - seems very low, I know alot of you are saying I should be working out energy etc, but does this work for a rough answer?
Cheers
Dont worry, I am not a student. this is for a actual problem, the force i am trying to calculate is part of a much bigger equation which will lead to me buying components and actually building something, hence the reason im only after a rough answer because its not massivly significant
Thanks for the replies, I am after only after a rough answer.
Jboggs, yes the rock is simply falling, so does that mean I can assume the acceleration is 9.81?
Cheers
no I just didnt think it was that relevent, sorry this is it:
I am trying to work out the impact force of a rock falling and hitting a surfce, dont need to worry about it bouncing or breaking up etc, just the basic force.
I was thinking KE/distance, (which i need velocity for the kinetc energy)...
Hi, I am trying to work out impact velocity, im tryng to use v^2=u+2*as
I know what my distance (s) is
I know what my inital velocity (u) is
But i dont know my acceleration
And I dont know my time
I was trying to use f=mg (i know what the mass is) then use a=f/m - but obviously end up with...
pietje, I tried that and set it to .123 but it still wont do 'trailing zeros' when it is a whole number.
Adding a note is'nt an option either as this is how the client wants it done unfortunatly.
Hi, Im trying to put dimensions on a drawing, which all have to be to 1 decimal place, which is fine for the dimensions which are X.XX, but some of them are simply 100mm, how do I make that 100.0mm. If I try to change it on the dimension pannel to .1 or even .12345 ect, nothing happens it just...
