Final answer:

To determine the force propelling the boat with a 4 MW engine moving at a constant velocity of 4.5 m/s, we use the power formula, which gives a result of approximately 888.89 kN.

Step-by-step explanation:

The question you've asked about the force propelling a boat with an engine producing 4 MW of power and moving at a constant velocity of 4.5 m/s involves using the formula for power, which is given by:

Power = Force x Velocity

To find the force exerted by the ship's engine, we rearrange the formula to solve for Force:

Force = Power / Velocity

Plugging in the given values:

Force = 4,000,000 W / 4.5 m/s

Force = 888,888.89 N

So the force propelling the boat is approximately 888.89 kN.
