Final answer:

The breaking distance on a dry surface at 60 mph is approximately 47.7 meters.

Step-by-step explanation:

In order to calculate the breaking distance on a dry surface at 60 mph, we need to know the deceleration rate of the vehicle. The example provided states that a car can decelerate at a rate of 7.00 m/s² on dry concrete. Using this information, we can calculate the breaking distance using the formula:

Breaking Distance = (Initial Velocity)^2 / (2 * Deceleration)

Converting 60 mph to m/s gives us an initial velocity of 26.8 m/s. Plugging in the values, we get:

Breaking Distance = (26.8 m/s)^2 / (2 * 7.00 m/s²) = 47.7 meters

Therefore, on a dry surface at 60 mph, it would take approximately 47.7 meters to stop.
