physics graph
How do I find y intercept of the negative slope ? I got a diff value and my sir got a diff one and idk how he got it

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Got it, also where is the velocity maximum ?
displacement-time graph?
Force displacement
Never mind I did not find y intercept , pls explain if u know it
Bro, Y intercept differ line to line
Ik, I asked for negative slope
@stormycloud is the negative slope-part of the graph passing thru 3,0?
because its a little off in the graph....
btw from the given line eqn, its clear its not lying at 3,0 rather its lying at 3.34,0 ☠️
Passing thru y,0 [ y is 10/3 after calculation ]
Thankyou so much
our sir did -150/2 = c / 10/3, is this because it is the same slope?
Also this please
Yup its the same thing!
Your teacher equated the slope of the eqn (the y2-y1 part) to the slope you would get with the y and x intercept, so yeah its same c=250
Was it mentioned for rectilinear motion?
Oh right right tysm, can’t believe I missed that point , ty again
The question is what is the maximum velocity and at which time was it attained
no probs! happy to help 😄
Our sir told max velocity is at point y, but idk how
yes but is it for a straight travelling body?
Yes, mass is 1.5kg
would also need the mass of the body right?
im assuming say "m" right?
oh cool let me write on paper and send
Oh okkk ty again, I just need to know why is it at that point
at the x intercept right?
Yup
ok so let me provide a cool analysis for it.if you look at the graph of the negative linear portion, what does it remind you of? yes the graph of force vs x for SHM! so in SHM, if you have studied, the maximum velocity is at the mean position, which would be represented by the x intercept.
another explanation would be mathmetical
Sorry but idk what is shm T-T
ok no worries! let me send the mathmetical version....
Thankyou so muchh
,rotate
hope it helps!
Omg tysmmm , it makes sense nowww
Also ik this is abt physics, but can u give me tips abt chem? These chem numericals are eating my brain , the calculations are so long and after I finish I figure out I missed something
man even i got that pain 😭 i would say to practise, like there are no shortcuts for calculations unfortunately. you can ask @iTeachChem for wonderful tips!
Ahh thankyou I understand 😭😭😭
you can add me in "doubt solved" section if the above solution helped....im trying to improve my doubts stats lol 😅
gotta get a good book, learn the process of solving questions. for instance, for all moleconcept and related stuff, need to know the basic definitions properly, you can solve any q under the sun.
similarly for eq and electro etc, gotta figure out derivations and what makes them tick, where do assumptions fail, again very solvable questions from anywhere if one does this
The thing is I understand the logics of the sum and stuff , but when I do it I calculate wrong or go wrong somehwre and it is worst when I can’t figure out where I went wrong, but yah ig only practising a lot can help me and my poor brain
Ofcccc, I’ll do itt :]
