Answer:

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

Step-by-step explanation:

Given;

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

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

The velocity of the ball relative the racquet ([tex]V_R_B[/tex]) is calculated as;

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

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