A ship of mass $3 \times 1 0^{6} kg$ initially at rest is pulled by a force of $5 \times 1 0^{5} N$ through a distance of 3 m. Assuming, that the resistance due to water is negligible, write the speed (in m/s ) of the ship

Answer:

Solution:

$a = \frac{F}{m} = \frac{5 \times 1 0 ^{5}}{3 \times 1 0 ^{6}} = \frac{1}{6}$ m/s $^{2}$

$v^{2} = 2 a s = 2 \times \frac{1}{6} \times 3 = 1$

$v = 1$ m/s
