A meter stick is pivoted about a frictionless pin through its left end. The moment of inertia of the meter stick through an axis passing at the pin is (1/3) mL2 where m is the mass of the meter stick and L is its length. The meter stick starts from rest at 20o below the horizontal and then it is released. What is the angular acceleration of the meter stick just at the instant it is released?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
