if the height of a playground slide is kept constant, will the length of the slide or the presence of bumps make any difference in the final speed of kids playing on it if a) the slide is frictionless b) the slide has kinetic friction?

a) if the slide is frictionless, length or bumps wouldn't matter because it acts like a free fall
b) if the slide had kinetic friction, it would work against the speed going down the slide so it would have an effect
