Показать описание
A bullet of mass 10g moving horizontally with a velocity of 400m/s strikes a wood block of mass 2kg which is suspended by light inextensible string of length 5m. As a result, the center of gravity of the block found to rise a vertical distance of 10cm. The speed of the bullet after it emerges out horizontally from the block will bea)100m/s b)80m/s c)120m/s d)160m/s
