An engine moves a motorboat through water at a constant velocity of 22 meters/second. If the force exerted by the motor on the boat is 5.75 × 103 newtons, what is the power of the motor?

answer

To find the power of the motor, we can use the formula:

Power = Force x Velocity

In this case, the force exerted by the motor on the boat is given as 5.75 × 10^3 newtons, and the velocity of the boat is given as 22 meters/second.

So, we can substitute these values into the formula:

Power = (5.75 × 10^3 N) x (22 m/s)

To calculate this, we multiply the two numbers together:

Power = 1.265 × 10^5 Watt

Therefore, the power of the motor is 1.265 × 10^5 Watt.

P=E/t=F•x/t=F•v
