A ship of total mass `m` is anchored in the middle of a river and water is flowing with a constant velocity `v_(0)`. The horizontal component of the force exerted on the ship by the anchor chain is `T_(0)`. If the anchor chain suddenly breaks, determine the time required for the ship to attain a velocity equal to `0.5 v_(0)`. Assume that the fricitional resistance of the water is proportional to the velocity of the ship relative to the water.

A

`(mv_(0))/(T_(0))ln2`

B

`(mv_(0))/(2T_(0))ln2`

C

`(3mv_(0))/(2T_(0))ln2`

D

None of these
