Answer:
Power=720[watt]
Step-by-step explanation:
We need to remember the definition of mechanical work which is equal to the product of the force applied by the distance traveled.
In this problem, we have to find the power which is defined as the work divided into the time in which such work is performed. This way if we have the displacement and the time, this will be the speed with which this work is done.
![Power= W/T\\T=time [s]\\W=work [J]\\Power = F*V\\where\\V=velocity [m/s]\\Power=1800 * 0.4 = 720 [watt]](https://img.qammunity.org/2020/formulas/physics/middle-school/yrn58t7hjt1ssocxsbxrlrj2ouk8x3qp5j.png)
