Question

A tennis ball is moving 30 m/s toward a player who swings a racquet at a velocity of 15 m/s toward the ball. What is the velocity of the ball relative to the racquet?

Answer 1

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.
