We would need to know what the friction is to affect to respond to this question.
ice can affect friction
Speed does not affect the force of friction.
viscous drag- the same as swimming or diving into a pool.
surface friction and sliding friction
An airplane flying through the air, a swimmer diving into a pool etc.
