Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.v=t^2
ya fir v=2t?
for either of these fucntions velcoity will always increase
y=x^2 aur y=x dono increasing fucntions hote hain for x>0
t^2 - 2t typo sorry
Draw a graph
aacha aapko AOD aata hai?
huh ? me abhi 11th me aaya hu
parabola plot karna aata hai toh karo, v on y axis, t on x
o ok
@Deleted User speed decrease maane v = negative
Speed up maane v = positive
wese acceleration related nai pucha ? to integrate krdu fn ko fir a positive ya negative aajayega
Wait NVM yes wo hi karna hai
ofc d(v)/dt kar ke a nikal lo, fir wo linear fucntion aa jayega wrt time
straight line, uski slope dekho kis t ke liye positive hai kis ke liye negative
2t -2
positive for t>1 therefore t=1 ke baad se speeding up
@Deleted User look
If sign of a and v are opposite then object is slowing down
If sign of a and v are same (both positive or both negative) then object will speed up
WAHI NA, pata nai mere dost ne kya ajeeb soln kra hai mera whi aaya
ruko uska soln bhejta
right side ka page
le bhai ye bhej de apne dost ko, yaha par wo parabola V =f(t) hai x= t maan le
Ye to mujhe lagrha andhadhun online se copy karliya
Usko bhi nahi pata usne kya likha
ig so v a se bada t 2 se bada av 0 se bada pata nai kya hai
ooooo ty bhai hogya 🙂
Bakwaas hai
Remember this @Deleted User
accha islie av>0 likha hai usne
oh uska sahi hai, usne av>0 aur av<0 leke krlia
Yes
ty bhai
