Answer:

The velocity of the ball relative the racquet is 15 m/s.

Step-by-step explanation:

Given;

velocity of the tennis ball, V_B = 30 m/s

Velocity of the racquet swung in opposite direction, V_R = 15 m/s

The velocity of the ball relative the racquet (V_R_B) is calculated as;

V_R_B = V_B-V_R\\\\\V_{RB} = 30 \ m/s - 15 \ m/s\\\\V_{RB} = 15 \ m/s

Therefore, the velocity of the ball relative the racquet is 15 m/s.
