Question
A body of mass 1 kg moving in the x-direction, suddenly explodes into two fragments of mass 1/8 kg and 7/8 kg. An instant later, the smaller fragment is 0.14 m above the x-axis. The position of the heavier fragment is -
Options
A.1/50 m above x-axis
B.1/50 m below x-axis
C.7/50 m below x-axis
D.7/50 m above x-axis
Solution
ycm = 0
× 0.14 + 
× h = 0
∴
= - 
⇒ h = - 0.02 below x-axis.
× 0.14 + × h = 0∴
= - ⇒ h = - 0.02 below x-axis.Create a free account to view solution
