I mean. Well. After a bachelors in physics i can basically go on to master in anything. But. If I go ahead with the aim of studying phyysics even for my majors. What I mean is that we know physics isn't always a lucrative career. I feel Studying a degree like physics and get a low/bad gpa is...
Iwe been planning on studying Physics for a few years now. And well. I just got done with my first year of uni. And Iwe had a horrible time of it. First year is undecided major hence general intro courses into everything. The curriculum and amount of work required at this uni is very tough. Much...
An inertial frame is one which is not accelerating.
i.e if I'm sitting in an accelerating bus or plane I'm not an inertial observer however if I am in a bus or train traveling at a constant velocity i.e zero acceleration then I am an inertial observer.
One thing Id like to ask here is that...
Okay on question two i can only get as far as drawing fbd for the particle. I realize I need to get sin/cos for tan but don't really know how to get there.
question three i have no idea. I don't understand. if the string is at an angle then does that mean tension has two components? If so...
Okay so my mechanics teacher is taking a rather mathematical approach to CM and its really confusing me. Can someone explain to me what this actually means?
d hat{r}/dt=dot{theta} hat{theta} and
d hat{theta}/dt=-dot{theta} hat{r}
I mean I know that anything with a hat on top is a...
Considering m2
T-Ff=m2a
T-μm2g=m2a
a= [F-μ(m1+m2)g]/(m1+m2)
Hence:
T= μm2g + m2[F-μ(m1+m2)g]/(m1+m2)
Hope I got it and typed it correct too. Thankyou for the help!
oh god. lol. sorry yes. the denominator should have the sum of the two masses. now how to approach the T
so this means there's only one correct equation for a. xd
I find the acceleration to be
a= [F-μ(m1+m2)g]/m1
Couldnt I also get another equation for a?
/e
Are you suggesting I use this a and put it in f=ma for m2?
Also since I can make FBD for either of the two masses and hence i could get two different equations for a. but both would be correct right?
I need help with part c. Since there is now a rough surface does that mean the acceleration of the two particles will be different? Is it wrong to simply add up the two masses and pretend that its one mass. And then find the net friction force and use f=ma directly?
I don't understand in which...
We have to graph these functions where they are real. (no need to graph where complex)
d)
For d I am getting a point at (1,0) and then half a c shaped graph opening towards the right. Is
this correct?
g)
For g I have 0 on the negative side. and a straight line in the first quadrant. :s...
what are those three conditions?
As far as I am concerned all Iwe been doing is checking for an indeterminate form and if its tjere applying L hopitals rule.
Also. When you guys suggested breaking it into two parts and not going for the second derivative, I remember my teacher saying...
