Dear Pratik

given

V= |t-2|

dx/dt = |t-2|

dx = |t-2|dt

oxdx  = o4|t-2|dt

x  = o2(2-t)dt  + 24(t-2)dt

=4

Please feel free to post as many doubts on our discussion forum as you can.
If you find any question Difficult to understand - post it here and we will get you
the answer and detailed  solution very  quickly.

All the best.

As we know that
At t=0  u=2 m/s     and at t=2  v=0 m/s
Therefore by v=u+at   we get,
0=2+a2   =)     a=-1m/s2
And by s=vt-1/2at2  we get
S= 0×2-1/2×-1×2×2     =)     s=2m ---------------1
So the first part is complete and now the second part starts
We know that at  t=2seconds   u=0m/s     and at     t=4sec   v=2m/s so total time =2sec
So by v=u+at
2=0+a×2       =)         a=1m/s2
Now by  s=ut+1/2at2
s= 0×2+1/2×1×2×2      =)         s=2m      -------------2
So by adding 1 and 2
We get distance travelled by bird =2+2=4 meters
And 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.
