This is the question. This is the FBD in the solution given. What i didn't understand is the sense of normal force. in the question mg force pulls particle down and according to my logic normal vector should be upwards in this conditions. but it is downwards in the given FBD. when i try to...

yeah meriam dynamics is kinda hard to get actually. i didn't like it but at the beginning of semester prof advised this book so i bought it. personally i prefer beer for dynamics. thanks for the answer by the way.

here is clear version i have equation (1) (3) and (4) just as in the book.

i also post what have i done at the end of my post. i did not understand what else do you need? i know solution is much easier with the energy but i am trying to get concept.

this is the question and solution given in the book solution i made below. only difference is i took x as opposite side that given in the book and wrote F=ma equation that way. as a result the left side of equation (3) directly turned negative. that caused difference in result but why? i mean...
