Question 3 (
Rod AO is rotating clockwise about O and accelerating uniformly from 20 rpm to 60 rpm in a 0.6 second period. At the same time, block B is moving inward at 0.2 m/s but decelerating at 0.5 m/s2. At a particular instance in time AO is
rotating at 45 rpm and is 30° below the horizontal as illustrated in figure Q3. At the same instant, block B is at a position 60 mm from O. Determine the nett acceleration of the block at this point in time.
