Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The wheel on a vehicle has a rotational inertia of

A	12
B	16
C	20
D	32

Explanation:

Detailed explanation-1: -Calculate the rotational inertia of a wheel that has a kinetic energy of 24400 J when rotating at 602rev/min. Rotational inertia of a wheel is, l = 12.3 kg.

Detailed explanation-2: -If more than one torque acts on a rigid body about a fixed axis, then the sum of the torques equals the moment of inertia times the angular acceleration: ∑ i i = I . ∑ i i = I .
