Kinetle ene ray sumple question: You serve a volleyball with a mass of os kit The ball leaves your hand with is speed of 30m/s

The kinetic energy of the volleyball can be calculated using the following formula:<br /><br />Kinetic Energy (KE) = (1/2) * mass * velocity²<br /><br />Where:<br /><br />* mass is measured in kilograms (kg)<br />* velocity is measured in meters per second (m/s)<br /><br />In this case:<br /><br />* mass = 0.25 kg (since 250g = 0.25kg)<br />* velocity = 30 m/s<br /><br />Plugging these values into the formula:<br /><br />KE = (1/2) * 0.25 kg * (30 m/s)²<br />KE = 0.125 kg * 900 m²/s²<br />KE = 112.5 kg⋅m²/s²<br /><br />Since 1 Joule (J) is equal to 1 kg⋅m²/s², the kinetic energy of the volleyball is:<br /><br />KE = 112.5 J<br />
