1. A block with mass 750g is thrown from 8m height with initial velocity vo = 10.7 î + 25.5 ĵ and a bullet with mass 200g hits and inserts the block with velocity 120 m/s at horizontal distance 25m at height h from ground. Block-bullet system strikes the ground at point A and moves in a frictional surface collide with a spring at point B which is kept fixed in one end as shown in figure.
