Question

Find the relative velocity of A with respect to B​

Answer 1

3 rad/s

Step-by-step explanation:

The relative angular velocity is the relative tangential velocity divided by the distance.

ω = (va − vb) / r

ω = (10 sin 30° m/s − -20 cos 60° m/s) / (5 m)

ω = (5 m/s + 10 m/s) / (5 m)

ω = 3 rad/s
