If a ship of mass ` 4 xx 10 ^( 7 ) ` kg initially at rest is pulled by a force of ` 5 xx 10 ^ ( 4 ) ` N through a distance of 4 m, then the speed of the ship will be (resistance due to water is negligible )

A

`1.5 ms^(-1)`

B

`60 ms^(-1)`

C

`0.1 ms^(-1)`

D

`5 ms^(-1)`

Text Solution

Verified by Experts

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