A block of mass 5 kg moves up on a smooth inclined plane with a velocity of 10 m/s in the direction shown. A bullet of mass 60 g travelling at 500 m/s strikes the block centrally and gets embedded in it. The velocity of the block and embedded bullet in m/s immediately after the impact is 30 1500 m/s (a) 12.54 at 30 (b) 13.84 at 51.78 (c) 13.84 at 30 (d) 15.62 at 78 10 m/s
