A meter stick is initially at rest in a horizontal position. It is free to rotate about the 50 centimeter point. A force of 25 Newton is applied to the 75 centimeter point in a direction that makes an angle of 30o below the 1.0 meter end of the meter stick. Another force of 20 Newton is applied to the 10 centimeter point in a direction that makes an angle of 40o below the 0 centimeter end of the meter stick.
a. Find the magnitude of the total torque on the meter stick?
b. If the moment of inertia of the meter stick is 0.33 kg-m2, find the magnitude of the angular acceleration of the meter stick?
