Formulate the answer of the following question

Question- A small grinding wheel has a moment of inertia of 4.0×105kg.m2.

Part 1- What net torque must be applied to the wheel for its angular acceleration to be 150rad/s2?

The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 38N.m. You plan to tighten the plugs by pulling on the end of a 20-cm-long wrench. Because of the cramped space under the hood, you'll need to pull at an angle of 130o with respect to the wrench shaft. With what force must you pull?

I need help to express the answer of the above question.
