A constant torque of 200Nm turns a wheel about its centre. The moment of inertia about this axis is 100kgm^2

AJT

To calculate the angular acceleration of the wheel, we can use the torque and moment of inertia. Angular acceleration can be found using the formula:

Angular acceleration = Torque / Moment of inertia

Given that the torque is 200 Nm and the moment of inertia is 100 kgm^2, we can substitute these values into the formula:

Angular acceleration = 200 Nm / 100 kgm^2

Simplifying this expression, we can cancel out the units of meters squared:

Angular acceleration = 2 N/kg

Therefore, the angular acceleration of the wheel is 2 N/kg.
