Calculate the rotational kinetic energy in the motorcycle wheel (Figure 10.38) if its angular velocity is 120 rad/s. Assume M = 12.0 kg, R1 = 0.280 m, and R2 = 0.330 m.
Step 1 of 3</p>
The wheel of a motorcycle is rotating with angular velocity of . By taking the mass of wheel as , inner radius and outer radius . We need to calculate the rotational kinetic energy in the motorcycle wheel.
Mass of wheel ,
Angular velocity ,
Rotational kinetic energy
Step 2 of 3</p>In order calculate the rotational kinetic energy, first we need to determine the moment of inertia(I) of the wheel using,
……….1The rotational kinetic energy of the wheel is given by,
Using equation 1,
