1057forgot to mention.... M=10 kg...
Consider a system as shown in the figure where the pulleys and the strings are ideal...
m1=1kg
m2=2kg
m3=.5kg
a)if frictionless find the acceleration of all the masses...
b)friction between each of the bodies is 0.1
c)friction between each of the bodies is 0.4

1a) acceleration(a)= g/4 [m1 mass falls down]
b) acc.(a)= 3g/10 [m1 mass falls down]
c) acc.(a)= 0 [becuz, friction is serlf adjusting force & it predominates in this case]
- Sourav Das sorry..
b) acc.(a)= 3g/20 [m1 mass falls down]Upvote·0· Reply ·2012-06-18 21:18:52
