A ship of mass `3xx10^7kg` initially at rest, is pulled by a force of `5xx10^5N` through a distance of `3m`. Assuming that the resistance due to water is negligible, the speed of the ship is

A

`1.5ms^(-1)`

B

`60 ms^(-1)`

C

`0.1ms^(-1)`

D

`5ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`a = (F)/(m) = (5 xx10^(4))/(5 xx10^(7)) = (5)/(3) xx 10^(-2)ms^(-2)`
`v = sqrt(2ax)= sqrt(2 xx(5)/(3)xx 10^(-3) xx 3)= 0.1ms^(-1)`
