Answer:
We need to find the radius R of sphere that has center at A as shown in figure.
From the given data and as per geometry shown in figure, R can be calculated as 10 m.
Angular velocity of Ball-A is 
when the two spheres are in contact, their angular velocities will be same at that instant.
hence ω2 = ω1 = 0.9 rad/s.
hence linear speed of ball-B = ω2 × 5 = 0.9×5 = 4.5 m/s
