Answer:
as the surface is smooth no rotation takes place and hence we can find the velocity of center of mass by simple equations for single particle. Hence , the velocity of center of mass is-
mgsinx = ma
a= gsin30
a=5m/s^2
velocity= 5 t
16=5 t^2
t^2 = 16/5
t= 4/5^1/2
t ~ 2
Therefore
v =10 m/s
Hope it helps.
