Final answer:
The turtle's acceleration is calculated using the change in velocity over time, resulting in 0.05 m/s², which is option A.
Step-by-step explanation:
The turtle's acceleration can be calculated using the formula for acceleration, which is a = (v_f - v_i) / t, where v_f is the final velocity, v_i is the initial velocity, and t is the time taken for the change in velocity. Plugging in the given values, we have an initial velocity (v_i) of 0.50 m/s, a final velocity (v_f) of 0.80 m/s, and a time (t) of 6 seconds.
The calculation would be as follows:
a = (0.80 m/s - 0.50 m/s) / 6 s = 0.30 m/s / 6 s = 0.05 m/s²
Therefore, the turtle's acceleration is 0.05 m/s², which corresponds to option A) 0.05 m/s².
