A body of mass `m=10^(-2) kg` is moving in a medium and experiences a frictional force `F=-Kupsilon^(2).` Its initial speed is `upsilon_(0)=10ms^(-2)`. If , after `10s`, its energy is `(1)/(8)m upsilon_(0)^(2)`, the value of `k` will be

`10^(-1)kgm^(-1)s^(-1)`

`10^(-3)kgm^(-1)`

`10^(-3)kgs^(-1)`

`10^(-4)kgm^(-1)`
