You have a bat-like echolocation system on your car, which emits a 20,000-hz frequency sound that returns to the car in 0.18 s after being reflected by another stationary car. the car is moving at 14 m/s toward the stationary car. find the distance that the moving car travels during the 0.18 s. express your answer with the appropriate units.

The car travel 2.52 m

Explanation:

This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.

Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.

    v = d / t

    d = v t

    d = 14  0.18

    d = 2.52 m

The car travel 2.52m

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
