Question: At the instant considered the radar antenna shown rotates about the origin of coordinates with an angular velocity = xi + yj + 2k

At the instant considered the radar antenna shown rotates about the origin of coordinates with an angular velocity Ï‰ = Ï‰xi + Ï‰yj + Ï‰2k . Knowing that (vA)y = 15 in./s, (vB)y = 9 in./s, and (vB)z = 18 in./s, determine (a) the angular velocity of the antenna, (b) the velocity of point A.
