1ya ....so wat.... if u know the soln plz post it....my answer is not matching with the answer given.....
three identicle pulleys each of mass M and radius R are arranged on a smooth horizontal tabe as shown in fig.....A force F is applied to pulley S while P and Q can rotate due to thread wound on them......
Q1.When centre of pulley S has moved through a distance D the Kinetic energy of the pulley S is......
Q2at this instant (when s has moved by disrtance D)what is the velo of centre of disc P
Q3.At this instant (when S has moved by disrtance D)what is the angular velo of dics Q....

11kkkkkk dude......... looks like u need to be associated with next rising star after goiit
first
since acc of com is ........ F/3m
so considering the other two masses......
T=F/3 tr=I@ and inertia is mr^2 (assuming it )
so anguar acc ... is F/3mr
now after time s moves a distannce x
for the mass m where the force applied theres no rotation
so
fx=1/2mv^2*3(since all three objects will hv same vel)+1/2iw^2(2 taking into account .... rotAation)
after that i think its a childs play.......... and the rest can be easily found........
