a block of mass m= 15.6kg is to be pushed with force F a distance of D=5.65m along an incline so that it s raised a distance h=3.86m in the process.Assuming frictionless surfaces.

Question

Determine:
A) The work done by the force F parallel to the incline to pst the block up at constant speed.
B)the power delivered by the force F after 8 seconds.

What i don't understand is if my teacher like mistyped and was suppose to be S instead of D. I know i start with the general definition of work which is W=FxSxCos⦶.
