A2.50 × 105 w motor is used for 26.4 s to pull a boat straight toward shore. how far does the boat move toward shore if a force of 4.20 × 104 n is applied by the motor?

The power of the motor is
2.50x10⁵ W
or 
2.50x10⁵ N m/s

The time it takes to pull the boat is
26.4 s

The force applied is
4.20x10⁴ N

The distance traveled by the boat is
2.50x10⁵ N m /s (26.4 s) / (4.20x10⁴ N)
 = 157.14 m

The center is basically the heart of it
