The amount of NOx emission produced by a household is required.
The total amount of NOx the household is responsible for is 91.06 kg.
1 car produces 11 kg of NOx per year.
Natural gas burning produces 4.3 g of NOx per therm.
Electric power plant produces 7.1 g of NOx per kwh.
2 cars will produce of NOx.
1200 therms of natural gas will produce
9000 kWh will produce
Converting all to kg and finding the total amount
The total amount of NOx the household is responsible for is 91.06 kg.

To solve this problem it is only necessary to apply the kinematic equations of angular motion description, for this purpose we know by definition that,
Where,
Angular Displacement
Angular Acceleration
Angular velocity
Initial angular displacement
For this case we have neither angular velocity nor initial angular displacement, then
Re-arrange for
Replacing our values,
Therefore the ANgular acceleration of the mass is
