```										Dear Pratik
given
V= |t-2|
dx/dt = |t-2|
dx = |t-2|dt
o∫xdx  = o∫4|t-2|dt
x  =  o∫2(2-t)dt  + 2∫4(t-2)dt
=4

```										As we know that At t=0  u=2 m/s     and at t=2  v=0 m/sTherefore by v=u+at   we get,0=2+a2   =)     a=-1m/s2And by s=vt-1/2at2  we get S= 0×2-1/2×-1×2×2     =)     s=2m ---------------1So the first part is complete and now the second part startsWe know that at  t=2seconds   u=0m/s     and at     t=4sec   v=2m/s so total time =2secSo by v=u+at2=0+a×2       =)         a=1m/s2  Now by  s=ut+1/2at2      s= 0×2+1/2×1×2×2      =)         s=2m      -------------2So by adding 1 and 2We get distance travelled by bird =2+2=4 metersAnd thats the answer for those who find the calculus in this question difficult.  And also feel free to ask any doubts involved in this solution.
