\text{Power}=12.635\ kW

Explanation:

The power P of work on the block of mass m=1400\ kg moving with a constant velocity v=1\ m/s up the plane inclined at an angle \theta=\tan^{-1}(3/4) is given as

P=\text{total force acting on the block down the plane}\times \text{velocity}

P=(mg\sin\theta+\mu mg\cos\theta) v

=mg(\sin\theta+mu\cos\theta)v

=(1400)(9.81)(3/5+(0.4) 4/5)\cdot 1

=12635.28 \ W

=12.635\ kW
