Question

the friction coefficient for rubber on wet concrete is 0.25 and dry concrete is 0.80. how does this affect the required stopping distance when it is raining? hint: less friction would increase stopping distance. the stopping distance would be the same on wet concrete the stopping distance would be much less on wet concrete the stopping distance would be much more on wet concrete

Explanation:

Friction opposes motion. A lower friction coefficient (0.25 for wet concrete vs 0.80 for dry) means less force to stop an object. So, more distance is needed to stop.

Answer:

the stopping distance would be much more on wet concrete
