if the radius of the CD is 6.0 cm and the angular velocity is 5.0 rad/s, what is the linear displacement of a point on the edge in 2.0 s?

well v=r*w
v linear velocity
v= 0.06*5=0.3 m/s
so linear displacement is
d=velocity * time = 0.3*2=0.6 m

How did you get the 0.3 m/s? @ghazi

Could you also help me find the angular displacement?

well angular displacement is theta = w* time = 5*2= 10 rad
