Final answer:

The power delivered by a 300-Newton force to a skier moving at 1.5 m/s is calculated using the equation P = F × v, resulting in 450 Watts.

Step-by-step explanation:

The student's question involves calculating the power delivered by a force to a skier moving at a certain velocity. Power is defined as the rate at which work is done or energy is transferred. It is given by the equation P = F × v × cos(θ), where P is power, F is the force applied, v is the velocity of the object, and θ is the angle between the force and the direction of motion. Since the angle is not specified, assuming the force is applied in the direction of motion (cos(θ) = 1), the power delivered can be calculated as follows:

P = 300 N × 1.5 m/s = 450 Watts.

Hence, the correct option from the provided choices is Option 3: 450 Watts.
