Power is equal to (Newtons x meters)/time, also known as the following equation...

P = Fd/t

Your force is 1800Newtons and your velocity is 0.4m/s
Velocity is equal to distance/time, also known as the following equation...

v = d/t

So your equation is basically P = Fv

P = 1800N x 0.4m/s

P = 720 Watts
