Step 1 :Given mass (m) = 2.1 kg and velocity (v) = 30.0 m/s
Step 2 :Calculate the kinetic energy (KE) using the formula: KE = 0.5 * m * v^2
Step 3 :Plug in the values: KE = 0.5 * 2.1 * 30.0^2
Step 4 :Calculate the result: KE = 945.0 J
Step 5 :\(\boxed{\text{Final Answer: The kinetic energy of the volleyball is 945.0 J}}\)
