Question

Suppose a highway curve is properly banked to eliminate friction for a speed of 45 mph. If your tires were bald and you wanted to avoid sliding on the road, you would have to drive:

a) at exactly 45 mph.
b) somewhat above 45 mph
c) somewhat below 45 mph.

Answer 1

To avoid sliding on a properly banked curve with bald tires, you would need to drive somewhat below 45 mph.

Step-by-step explanation:

When a highway curve is properly banked to eliminate friction, a car can safely travel through the curve without sliding. In this scenario, the curve is specifically banked for a speed of 45 mph.

However, if your tires were bald, the friction between the tires and the road would be reduced, increasing the likelihood of sliding. To avoid sliding in this situation, you would need to drive somewhat below 45 mph to ensure better control and reduce the risk of a slide.
