Final answer:
The boat's acceleration is calculated using the change in velocity over time. With an increase from 15 m/s to 25 m/s in 10 seconds, the acceleration is 1 m/s².The boat's acceleration is 1 m/s².
Step-by-step explanation:
The boat's acceleration can be calculated using the formula for acceleration a = (v_f - v_i) / t, where v_i is the initial velocity, v_f is the final velocity, and t is the time over which the change in velocity occurs. In this case, the boat speeds up from an initial velocity of 15 m/s to a final velocity of 25 m/s over a period of 10 seconds.
Plugging the values into the formula, we get a = (25 m/s - 15 m/s) / 10 s = 10 m/s² / 10 s = 1 m/s². Therefore, the boat's acceleration is 1 m/s².
