Fluid Frictional Force acting on aircraft is
Now by newton's laws of motion,
Comparing above two equations, ( as we neglected air friction)
Integrating above equation, we get
( where C= constant)
( because: )
................(1)
Now given, at t=0s, v= 20 m/s
Using above values in equation,
or
Putting above in equation1 ,
Now when v= 0, then value of time is
Using given values,
( ANS)
An aircraft carrier weighting 6 times 10^7 kg is traveling at 20 m/s on the open...
