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

Respuesta :

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
