Answer:

Explanation:
Taking summation of force at perpendicular to the plane




Taking summation along the plane, therefore we have


from equation 1 and 2 we have





Answer: 0 miles.
Explanation:
First let's define what the displacement is:
The displacement is defined as the difference between the final position and the initial position.
So, if for example, you start at your house, then go to a store, and then go back to your house, your total displacement will be zero, because the initial position and the final position are the same.
Then when the car reaches the final line, it will be in the same place that it started (because this is an oval track, so the finish line connects with the starting point)
Then the total displacement is 0miles.
