To Calculate: The displacement of the car.
Answer to Problem 28PP
Explanation of Solution
Given:
The car has an initial velocity of
Formula used:
Final velocity with constant acceleration can be obtained by:
Where,
The distance traveled by an object with a constant acceleration can be obtained by:
Here, d represents displacement, v represents velocity, t represents time and a is the acceleration.
Calculation:
First find the time elapsed:
Negative sign of acceleration is used since it is acted towards west direction, opposite to the direction of motion of the car.
Now, assume that the initial position of the car is
Conclusion:
Thus, displacement of the car is
