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

A

`10^-14 kg m^-1`

B

`10^-1 kg m^-1 s^-1`

C

`10^-3 kg m^-1`

D
