A uniform 3-kg and 1.5-m rod pivoted at O is released at rest from the horizontal position, swings down and impacts with a block of 4 kg at the end A on a frictionless surface, as shown in Figure 1. Knowing that the impact is perfectly plastic and the block is connected to an initially unstretched spring of 700 N/m, determine А o 3 kg 1.5 m 4 kg 700 N/m Figure 1 (7 marks) (a) the speed of end A just before impact; (b) the speed of block just after impact; (7 marks) (c) the natural angular frequency of the resulting vibration; (8 marks) (d) the maximum compression of spring.
