Answer 1

Answer:

$\huge\underline\mathtt\red{Answer}$

50 Rad/s

$\huge\underline\mathtt\green{Explanation}$

angular velocity equals the relative linear velocity divided by radius

ω=(Vb-Va)/r...............(1)

the angular velocity of point A with respect to point C is:

substituting the values in equation (1)

ω=(100m/s-50m/s)/1m

ω=50 Rad/s

the angular velocity of point A with respect to point O is:

ω=(100m/s-0m/s)/2m

the angular velocity of A with respect to B is:

ω=[100m/s-(-100m/s)]/4m

ω=50 Rad/s

.
