Final answer:
To calculate the force exerted by the racket on the tennis ball, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. The force exerted by the racket on the tennis ball is 1 Newton.
Step-by-step explanation:
To calculate the force exerted by the racket on the tennis ball, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration.
First, we need to convert the racket's velocity from kilometers per hour to meters per second. Since 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds, we divide 65 kilometers per hour by 3.6 to get approximately 18.06 meters per second.
Next, we can calculate the force using the formula F = m × a, where F is the force, m is the mass of the tennis ball (0.1 kilograms), and a is the acceleration (10 meters per second squared). Therefore, the force exerted by the racket on the tennis ball is 1 Newton.
