Question

A particle intitially at rest moves along x axis.It is subjected to an acc. which varies with time as a=2t+s.Its velocity after 2s is??

Answer 1

@Mashy @shubhamsrg

Answer 2

\[\LARGE V=t^2+\frac{s^2}{2}\]

Answer 3

@DLS >.<
@RnR (of course)

Answer 4

i thought i should let him study..hmm..:|

Answer 5

\[\LARGE V(2)=4+\frac{s^2}{2}\]

Answer 6

kuch to galat kiye ho.. recheck!

Answer 7

\[\LARGE \frac{4t^2}{2}\] hoga?
i though constant is taken out in int..idk INT!

Answer 8

bye.

Answer 9

EFF YOU.

Answer 10

:D

Answer 11

both sides dt se multiply karke integrate kiye ho na?

Answer 12

sdt ka integral kaise kar liye? o.O

Answer 13

no? :/

Answer 14

kya kiye ho?

Answer 15

integrate :o

Answer 16

step likho..

Answer 17

a ka sahi tha?

Answer 18

kiske respect me kiye ho ? dt right ?

Answer 19

respect?:P pata nhi o.o

Answer 20

adt ko integrate karke v likhe ho na ?

Answer 21

\[\LARGE dv=adt\]
\[\LARGE V=\int\limits_{0}^{t}(2t)dt+\int\limits_{0}^{t}(s)dt\]

Answer 22

2t ka integral sahi hai
sdt ka kaise kar diye? o.O

Answer 23

pata nahi :P

Answer 24

s constant hai?

Answer 25

ohh, const hai kya? s displacement hai na?

Answer 26

wahi to to kaise karenge integrate

Answer 27

disp hi hoga.

Answer 28

ha to nahi karenge! ^_^

Answer 29

nevermind

Answer 30

V=2t^2+s

Answer 31

V=8+s

Answer 32

kya? const. maan liye? -_-
tab bhi galat int. hai :|

Answer 33

\[\LARGE s=\frac{1}{2} \times (2t+s)(4)\]

Answer 34

integrate nahi kiya to const he to maana?:/ const nahi maana par wtf chod

Answer 35

sdt ka integral st ho jayega.

Answer 36

okay

Answer 37

ab agar const hai, to t=0 pe v=0 given hai, is se s nikal lo

Answer 38

fir t=2 pe v solve kar lo

Answer 39

V=8+2s hoga?

Answer 40

ha

Answer 41

distance kaise?

Answer 42

and @Mashy alive?:o

Answer 43

dist nahi maan rahe hai ham log, use const. maan rahe hain.

Answer 44

wtf?:/

Answer 45

t=0 pe v=0, yaha se s nikala ?

Answer 46

ohh,, s nahi nikal payega yaha se! :3

Answer 47

-_-

Answer 48

iska ans pata hai ?

Answer 49

no :/

Answer 50

a=2t+s

hmm, disp hi hoga..
ye to ajeeb sa ques hai? sahi hai na ques? :|

Answer 51

yes,sahi hai tabhi post kiya :|

Answer 52

ajeeb sa diff eqn baneja, na malum babu
@Mashy ^_^

Answer 53

tab tak ill post next ques :P

Answer 54

what is s?

Answer 55

lol..ramayana khatam bhaiya puche sita kaun :o
