To solve this problem, we'll use the formula for acceleration:

acceleration (a) = (final velocity - initial velocity) / time

Given:

initial_velocity = 46 # m/s final_velocity = 9 # m/s time_interval = 9 # seconds

Calculating acceleration

acceleration = (final_velocity - initial_velocity) / time_interval rounded_acceleration = round(abs(acceleration), 1) rounded_acceleration4.1

Would you like more details or have any questions? Here are 5 related questions you might find interesting:

1. What is the direction of acceleration in this scenario?
2. How do you determine if acceleration is positive or negative?
3. What would the final velocity be if the time interval was doubled?
4. How would you calculate the distance traveled during this deceleration?
5. How can you determine if the car comes to a complete stop?

Tip: When dealing with deceleration, remember that the acceleration value will be negative, but magnitude is always positive.
