A locomotive of mass 'm' starts moving so that its velocity varies as `V = Ksqrt(S)` , where 'K' is a constant and 'S', is the distance traversed. The total work done by all the forces acting on the locomotive during the first 't' seconds after the start of motion is,
A
`1/2mK^(4)t^(2)`
B
`1/4mK^(4)t^(2)`
C
`1/8mK^(4)t^(2)`
D
