The time it takes the block and the sphere to reach the bottom of the plane, uniform sphere and a block are placed at rest is 3 second
a=gsinθ1+K2R2
I=25MR2=MK2
K^2/R^2=2/5
θ=g×sin30∘1+25
a=5/7g×12
=57×9.8×12

s=ut+12at2,
15.75=0+12×3.5×t2
t^2=15.75×23.5=9
t=3s
Time is described by physicists as the progression of events through the past, present, and future. A system is essentially timeless if it doesn't change. Time may be viewed as the fourth dimension of reality when describing events that occur in three-dimensional space. Time is something we cannot see, touch, or taste, but we can calculate how much of it has passed. Time is constant everywhere in classical mechanics. The timekeeping mechanisms continue to be accurate. Time is relative, however, as demonstrated by Einstein's special and general theories of relativity. It depends on the viewpoint of the observer. According to the theory of time dilation, intervals between events lengthen as one gets closer to the speed of light (dilates).
