Explanation:
Let’s solve this step by step, like we’re talking through it together.

Step 1: What are we looking for?
We need to find the average acceleration of the roller coaster car.

Step 2: What do we know?
- Initial speed (starting speed) = 4 m/s
- Final speed (at the bottom) = 22 m/s
- Time it took = 3 seconds

Step 3: Use the formula for acceleration:
Acceleration = (Final velocity – Initial velocity) ÷ Time

Step 4: Plug in the numbers:
Acceleration = (22 – 4) ÷ 3
Acceleration = 18 ÷ 3
Acceleration = 6

Step 5: Don’t forget the units!
Since speed is in meters per second (m/s), and time is in seconds (s), acceleration is in meters per second squared → m/s²

So, the answer is 6 m/s². That means every second, the car sped up by 6 meters per second. Pretty fast!
