Question

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?

Answer 1

@guillefix @ghazi

Answer 2

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

Answer 3

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

Answer 4

Ok, I see, thanks.

Answer 5

Could you also help me find the angular displacement?

Answer 6

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

Answer 7

Your an awesome help.

Answer 8

you are welcome :D
