How to handle these types of graphs (vel/displacement or vel/distance graphs)
it would be very if you tell me this all here or just suggest a video from internet
Thanks

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.What are we supposed to find
for now i got graph related
watch mr sir kinematics graphs , best possible explanation
not now bahut hw hai
thanks will surely watch when i get time
you from pw online too?
4th one ig?
4?
nope
yeah
yes
try to use a=vdv/dx
ull get it
oh just needed that thanks
this one also pls
np
1?
You can do it by observing too. After x=200, uniform velocity, indicating 0 acceleration
how i am getting 2 idk why tan theta would be = 60/30 ig?
try to find slope
using differentiation , ull see it instantly
oh thanks
but slope i am getting is 2 why its wrong?
nah for this q u can just apply v^2=u^2+2as
u get direct ans xd
v^2/x ko differentiate karo
2vdv/dx
a=vdv/dx
....
u can but why go for unnecessary calc
abhi bhi nhi samaj aya pura answer hi btaado💀
1 hai na answer ?
unnesecary kaise, its easier bro
squaring and all
80=20+(2x30xa)
they ahve given the squared velocity, which is exactly why its easier
oh right
makes sense
still the differentiating one is also valid
OP u can follow this
as a non coaching student my "basic math" is ass so
its easier to grasp mentally
yes but teach me the diff method too plssss
thenks brotha
Make equation of v as a function of x and then apply a=vdv/dx to get eqation of a
Shall we close this one out?
