Question

1. safe driving procedures require a driver to slow down when the surface of the road is covered with water, snow or ice. referring to the table of coefficients of friction explain why.

materials	coefficient of static friction
tire on wet concrete	.8
tire on ice	.05

Explanation:

Step1: Understand friction concept

Friction helps in vehicle - control. Lower coefficient means less friction.

Step2: Analyze table values

Coefficient of static friction for tire on dry concrete is 1, on wet concrete is 0.8 and on ice is 0.05.

Step3: Relate to driving

When road is wet, snowy or icy, friction is low (as seen from coefficients). Low friction reduces vehicle's ability to stop or turn safely. So, driver must slow down.

Answer:

When the road surface is covered with water, snow or ice, the coefficient of static friction between the tire and the road surface is lower compared to a dry - concrete road surface (e.g., 0.8 for wet concrete and 0.05 for ice vs 1 for dry concrete). Lower friction means less traction, reducing the vehicle's ability to stop or turn effectively. To maintain safety and control, the driver should slow down.
