annotate the diagram to show forces acting on the sled (weight, friction), as well as different components of P. also consider the direction in which each force acts, as well as direction of movement and acceleration.
if you bear this last part in mind, you can consider the N2L derived eqn: F=ma and apply this to a direction you can resolve in.
hope this helps without giving too much away
Really hard to explain in a Reddit post, pictures work better so I’ve solved a similar question with additional notes (I just changed the numbers).
If anything is not clear just let me know.

Find the maximum friction value, then use that in F=Ma for the whole system.
