Question

kayakers wax their boats to?

Answer 1

I think is to reduce their input force.

Answer 2

A kayaker uses a paddle to exert a force on the water. Waxing the boat doesn't really affect that action.

Rather, the waxing smooths the surface of the boat which decreases the friction it has with the water surface.

This means for the net force of the kayak: Fnet = F - Ff, Ff would get smaller, so the kayaker moves further with his stroke.

If there was a specific, constant Fnet the kayaker was looking to achieve, then you would be correct. Ff would decrease, so the kayaker could decrease his F accordingly. I think in most cases though the kayaker keeps his F constant, so if Ff decreases, Fnet increases. He just gets more out of his stroke.

Answer 3

@Pompeii00 is it to reduce the work output? or to reduce input force? i have two answers

Answer 4

@bernard96 can u help me?

Answer 5

Sorry for the large delay.

It would reduce the work output. Another way of saying "work output" is "resistance to the input work".
