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.

Solution 24CQ

Step 1 of 3

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.

Given data,

Mass of wheel ,

Inner radius,

Outer radius,

Angular velocity ,

To find
