Please tell write answe r for 50 point

Answer 1

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
