coach Farris demonstrates how to serve a volleyball. She hits the ball with a force of 7N and the volleyball accelerates at 10.0 m/squared

To determine the mass of the volleyball, we can use Newton's second law of motion, which states:

Force = mass x acceleration

Rearranging the equation to solve for mass:

mass = Force / acceleration

mass = 7N / 10.0 m/s^2
mass = 0.7 kg

Therefore, the mass of the volleyball is 0.7 kg.
