hey guys, i'm in the middle for revising for a dynamics paper in January. I'm in the middle of a 1st year BSc Physics degree. Looking through some past papers, there are questions that i can do, and there are questions that i am unable to do. These are usually question where you have to derive. I am going to write down one of the questions that are causing me problems and i was wondering if you could help me on how to answer it. Q. An object moving along a horizontal surface reaches the foot of a plane inclined at an angle [tex]\vartheta[/tex] to the horizontal with a speed u. If the coefficient of friction between the object and the plane is [tex]\mu[/tex] show that the object will come to rest a distance d up the plane where d = u2 / 2g (sin[tex]\vartheta[/tex]) + [tex]\mu[/tex]cos[tex]\vartheta[/tex] I am a diagnosed dyslexic, not using it as an excuse, i will always try my best, but this is not sinking in, can you please help.
