    Actually the question is that a child goes down a slide, then what is the work done by the slide? Is it asking the work done by the normal reaction on the child?

    The normal force does no work because the dot product of F and dx is zero (there is no motion in the direction of the normal force.) Consider friction, however. It is in the direction opposite motion.

    since the friction is zero w=f.ds become zero .

    The work done by the slide is the work due to the friction force
