A ship of mass `3xx10^(6)` kg initially at rest is pulled by a force `6xx10^(4)N` through a distance of 4m. The speed of the ship is (Assume resistivity of water is negligible)

A

1.5 m/s

B

20 m/s

C

0.5 m/s

D

0.4 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
`a = F/m = (6xx 10^4)/(3xx10^6) = 2xx 10^(-2) ms^(-2) , u=0`
Now, `v^2 - u^2 + 2as`
`v^2 = 0 + 2 xx 2 xx 10^(-2) xx 4`
`v^2 = 16 xx 10^(-2) = 0.16`
`v= 0.4 ms^(-1)`
