Review Two identical 19-kg spheres are attached to the light rigid rod, which rotates in the horizontal plane centered at pin O. (Figure 1) Figure < 1 of 1 > If the spheres are subjected to tangential forces of P = 10 N, and the rod is subjected to a couple moment M = (8t) N-m, where t is in seconds, determine the speed of the spheres at the instant = 4 s. The system starts from rest. Neglect the size of the spheres. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) P 10 N 0.5 m M = (8) N-m ?
