Answer
The kinetic energy of the volleyball can be calculated using the following formula:Kinetic Energy (KE) = (1/2) * mass * velocity²Where:* mass is measured in kilograms (kg)* velocity is measured in meters per second (m/s)In this case:* mass = 0.25 kg (since 250g = 0.25kg)* velocity = 30 m/sPlugging these values into the formula:KE = (1/2) * 0.25 kg * (30 m/s)²KE = 0.125 kg * 900 m²/s²KE = 112.5 kg⋅m²/s²Since 1 Joule (J) is equal to 1 kg⋅m²/s², the kinetic energy of the volleyball is:KE = 112.5 J
