Answer:
If we take the position of ship
′
A
′
as origin then position and velocities of both ships can be given as:
V
A=(30 +50 )km/hr
V
B=−10 km/hr
A =0 +0
B=(80 +150 )km
Time after which distance between them will be minimum
t=−BA
BA
where
r
BA =(80 +150 )km
V
BA=−10 −(30 +50 )(−40 −50 )km/hr
∴t=− ∣−40 −50
(80 +150 )⋅(−40 −50 )
=
4100
3200+7500
hr= 4100/10700
hr=2.6 hrs.
