PhysicsMedium70×since 2002Q8576A body of mass m = 10^–2 kg is moving in a medium and experiences a frictional force F = –kv². Its initial speed is v₀ = 10 ms^–1. If, after 10 s, its energy is 18mv02{1 \over 8}mv_0^281mv02, the value of k will be:A10⁻¹ kg m⁻¹ s⁻¹B10⁻³ kg m⁻¹C10⁻³ kg s⁻¹D10⁻⁴ kg m⁻¹Check answerSkip
