10. What is the Kinetic Energy of a 100 kg object that is moving with a speed of 12.5 m/s

The formula for kinetic energy (KE) is given by:<br /><br />\[ KE = \frac{1}{2} m v^2 \]<br /><br />where \( m \) is the mass of the object and \( v \) is its velocity.<br /><br />Given:<br />\( m = 100 \) kg<br />\( v = 12.5 \) m/s<br /><br />Plugging in the values:<br /><br />\[ KE = \frac{1}{2} \times 100 \times (12.5)^2 \]<br />\[ KE = 50 \times 156.25 \]<br />\[ KE = 7812.5 \, \text{Joules} \]<br /><br />So, the kinetic energy of the object is \( 7812.5 \) Joules.
