Unformatted text preview: M is applied about shaft CD of the frame, determine the speed of the blocks at time t . The mass of the frame is negligible, and it is free to rotate about CD . Neglect the size of the blocks. Given: M 0.4 kg = a 0.3 m = v' 2 m s = M 0.6 N m = t 3 s = Solution: 2 aM v' M t + 2 aM v = 370...
