Best ResponseYou've already chosen the best response.0rotational kinetic energy of spherical shell + rotational K.E. of pulley + K.E. of object = change in P.E. of object

Best ResponseYou've already chosen the best response.0since string is not stretchable: velocity of object = angular speed of shell* Radius of shell = angular speed of pulley * radius of pulley. now put the known values and get the answer.

Best ResponseYou've already chosen the best response.2\[I_{sphere}=2/5MR^2\] then, for the sphere \[1/2(2/5MR^2)w_{sphere}^2=1/5Mv^2\] and for the pulley: \[1/2Iw_{pulley}^2=1/2I(v/r)^2\] with the data given in the drawing: \[mgH=v^2[m/2+M/5+I/(2r^2)]\]
