A bullet of mass $10 g$ moving horizontally with a velocity of $400 m s^{- 1}$ strickes a wooden block of mass $2 k g$ which is suspended by a light inextensible string of length $5 m$ . As a result, the center ofgravity of the block is found to rise a vertical distance of $10 c m$ . The speed of the bullet after it emerges out hirizontally from the block will be

100m/s

80 m/s

120 m/s

160 m/s
