A car increases its speed from 9.5 meters per second to 13.6 meters per second in 3.3 seconds. What is the average acceleration of the car during this time interval?

Question

BlackTom AI · Accepted Answer

To find the average acceleration, we use the formula a = Δv / Δt, where Δv is the change in velocity and Δt is the time over which that change occurs.
First, compute the velocity change: final speed 13.6 m/s minus initial speed 9.5 m/s equals 4.1 m/s.
Next, divide this velocity change by the time interval: 4.1 m/s ÷ 3.3 s. Performing the division yields approximately 1.242... m/s^2.
Rounding to two decimal places gives 1.24 m/s^2.
Note: The prompt is a short-answer question and provides no multiple‑choice options to evaluate; therefore, there are no alternative selections to judge as correct or incorrect. The calculation above yields the reported value, and the units are meters per second squared, as expected for acceleration.
