Q02 V There is a rod (1D-object) of mass density 2=1.50 kg/m, mass m1, and length L=1.88 m which connected with two m solid spheres at both ends of the rod of radius R=22 cm and mass of each m2=1.80 kg. Combined object rotates L/2 L/2 around y-axis (y is the fixed axis, on xz plane). Combined object starts from rest (01=0) and rotates with angular 2R 2R acceleration of a = 2.5 rad /s2. a) Find an algebraic equation (with only given variables) for the total moment of inertia of combined object (4 points) and then find numerical value by using given information? (1 points) b) Find the angular velocity of combined object after t=3.0 s? (2 points) c) Write down an algebraic equation (with only given variables) for the total rotational energy of the combined object (2 points) and then find the numerical value at t=3.0 s. (1 points)
