A shell of mass `4kg` moving with a velocoity `10m//s` vertically upward explodes into three parts at a height `50m` from ground. After three seconds, one part of mass `2kg` reaches ground and another part of mass `1kg` is at height `40m` from ground. The height of the third part from the ground is : `[g=10m//s^(2)]`

A

50 m

B

80 m

C

100 m

D

none of these
