A ship of mass \( 3 \times 10^{7} \mathrm{~kg} \) initially at rest...

A ship of mass ( 3 times 10^{7} mathrm{~kg} ) initially at rest is pulled by a force of ( 5 times 10^{4} mathrm{~N} ) through a distance of ( 3 mathrm{~m} ). Neglecting friction, the speed of the ship at this moment is : (1) ( 3.0 mathrm{~m} / mathrm{s} ) (2) ( 1.5 mathrm{~m} / mathrm{s} ) (3) ( 0.1 mathrm{~m} / mathrm{s} ) (4) ( 2 mathrm{~m} / mathrm{s} )
