Answer 1

soll:- Mc=0.25 Mpp = 0.20 (fs) nam = MSN -- 0-25 x 50 -) 12-5 N Fonts3" 36-5HK Pre SON GN so

a) 10 E 12a5 When W2 = lon Tz W2 CLON It will slide downward 36 friction will be kinetic tz MAN =) 0.2x50 ) 10N friction will act op co the incline & 36.5

W zo -Fret b) W2=zon. R22.5 هو واحه de اخر امريكا friction willl be lenetic up tue. forchon will act we the incline Plane - Frete 360 5 fx Mx R = 0.2% 5o = 10N Fret o) 36.5 - ( 2o f10 )z) 6.5 N c) W2 = 30. N L 5 [fs mon = 1205 N 365 since static friction will act up the plone - Fret = 30ties at 42.5N It means it will not more. friction will be static fr is self adjusting so to = 36.5-30) 6e5n up the plane 2 (نی لم ۶۰ = ودا ا - Yo - Frete fachon will be 365 einetic static fo=1205 since Fret was along up the incline go to will act below the incline bloic will not slide frichon ff) a yox 36.5 =) 3.5 N daun fel Plane

Answer 2

This really helps when it comes to ANY physics
