Final answer:
To calculate the average acceleration of the bug on the interval [1,4], you need to find the velocity change and time change, then use the formula average acceleration equals velocity change divided by time change.
Step-by-step explanation:
To find the average acceleration of the bug on the interval [1,4], you would first determine the change in velocity (Δv) of the bug during this time. Then, you would determine the change in time (Δt), which is the duration of the interval. With these values, you can calculate the average acceleration using the formula à = Δv / Δt, where à represents the average acceleration.
