A ship of mass `3xx10^(7)` kg at rest is pulled by a force of `5xx10^(4)` N through a distance of 3m. Neglecting water resistance, the speed of ship is:

A

1.5 m/sec

B

16 m/sec

C

0.1 m/sec

D

5 m/sec

Text Solution

Verified by Experts

The correct Answer is:
c
K.E.=Work done =F.x.
`1/2,mv^(2)=F.x.`
`implies v=sqrt((2F.x)/(m))=sqrt((2xx5xx10^(4)xx3)/(3xx10^(7)))=0.1 ms^(-1)`
