A ship of mass `3 xx 10^(7)` kg initially at rest is pulled by a force of ` 5 xx 10^(4)` N through a distance of 3 m. Assuming that the resistance due to water is neglible, what will be the speed of ship ?

Options

A. 0.1 m/s
B. 1.5 m/s
C. 5 m/s
D. 0.2 m/s

Answer

a

Explanation

`a = 5 xx 10^(4) // 3 xx 10^(7) = (5//3) xx 10^(-3) ms^(-2)`
`v^(2) = 2 as = 2 xx (5//3) xx 10^(-3) xx 3 = 0.1 ms^(-1)`
