A wheel spins at 2.3 m/s. What would be the Connecticut energy, if the mass of the wheels were 7.2 kg?

In this case energy will be the kinetic energy given by the formula;

1/2mv², where m is the mass and v is the velocity;

Velocity = 2.3 m/s and the mass is 7.2 kg

Hence;

= 1/2 * 7.2 * 2.3²

= 19.044 Joules
