Question

the choice of materials for an exciting playground slide should ____________. (1 point)
○ have a small coefficient of static friction between cloth and the slide material
○ have a small coefficient of kinetic friction between cloth and the slide material
○ have a large coefficient of kinetic friction between cloth and the slide material
○ have a large coefficient of static friction between cloth and the slide material

Explanation:

For an exciting playground slide, one wants the rider to slide down easily. Kinetic friction acts when the rider is in motion on the slide. A small coefficient of kinetic friction means less resistance to the motion, allowing for a faster and more exciting slide. Static friction is relevant for starting to move, but kinetic friction affects the sliding motion itself.

Answer:

have a small coefficient of kinetic friction between cloth and the slide material
