Two ropes are puling a large ship at rest of mass `1xx106kg` into harbour. Rope A exerts a force of `40,000N` and rope B exerts a force of `30,000N`.
The time for the ship to travel `6m` to the the dock is

A

`1min 30 s`

B

`1min`

C

`40 s`

D

`20 s`

Text Solution

Verified by Experts

The correct Answer is:
D
`s=1/2at^2impliest^2(2s)/a=(2xx6)/0.03=2xx200`
`t=20s`
