1) First, let's calculate the value of deceleration a that the car can achieve, using the following relationship:

where S=67 m is the distance covered, vf=0 is the final velocity of the car, and vi=15 m/s is the initial velocity. From this we can find a:

2) Then, we can assume this is the value of acceleration that the car is able to reach. In fact, the force the brakes are able to apply is

This force will be constant, and since m is always the same, then a is the same even in the second situation.
3) Therefore, in the second situation we have a=-1.68 m/s^2. However, the initial velocity is different: vi=45 m/s. Using the same formula of point 1), we can calculate the distance covered by the car before stopping:

D.On the ocean floor. When tectonic plates move, They move along the ocean floor, which is the crust, and It causes earthquakes and volcanoes and also caused Pangea to break apart and become what it is now The seven continents.
Answer:
Forgive me if I'm wrong but I think the answer is C.
Explanation:
I say this because liquid water is H20 (a combination of two elements) and Oxygen is a singular element. Compound is defined as a thing that is composed of two or more separate elements and thus, I think it's C.
