Oh I was not even thinking that the friction force was 3.8 N. I was thinking that is was the force applied or something. I get it now. Thank you very much for your help, I really really appreciate it
Oh ok, yes it does help. I can see where you get the acceleration to be equal to zero.
So
186.2 - 186.2 = ma = 0
So how do I solve for friction?
OK hold on. To calculate the coeffecient of friction I will have to divide 3.8N/186.2N to give me 0.02 as the coeffecient. It's the...
OK I don't get the part where you are explaining
Fnet = N - mg = ma = 0
N signifies Newtons, right? As in 3.8N, right?
I did this then
Fnet = 3.8N - 186.2 = -182.4 = 0
How does it equal zero?
Or is it
Fnet = 3.8N - 190 = -186.2 = 0 and that means that the 186.2 will...
I have this assignment to do and I am stuck on finding the force of friction acting on a curling rock.
The mass is 19Kg and the acceleration is -0.2m/s^2
I calculated the force applied using F = ma
This gave me -3.8N
I let negative rep force applied
positive rep force of...
