Hi Pete Thanks for all you do, I will be very grateful if you could break down your reasoning further on how you approached the angle for N.

Hello, Great very helpful. but how do we know when to consider an object's reaction force when on an inclined surface? Up to this point in the chapter we have had to consider Reaction of the surface on the mass at the point it is so how do we know when to disregard it at that particular point? I hope you can help!
