Final answer:
To determine a 'safe speed' for a boat, various factors such as boat size, acceleration, collision avoidance, and drag need to be considered.
Step-by-step explanation:
The determination of a 'safe speed' for a boat involves considering several factors. These factors include the boat's size, acceleration capabilities, the desire to avoid collisions with docks, and the drag on the boat at low speeds. One important concept to note is the relationship between the force of propulsion (Fp) and the weight of the ship. In this example, Fp is less than 1/600th of the ship's weight, indicating a relatively small drag. Therefore, considering these factors and the boat's design, a 'safe speed' can be determined to prevent any potential accidents or damage.
