Momentum and CollisionHard
Question
A body A of mass M while falling vertically downwards under gravity breaks into two parts; a body B of mass 1/3 M and a body C of mass 2/3 M. The centre of mass of bodies B and C taken together shifts compared to that of body A towards
Options
A.depends on height of breaking
B.does not shift
C.body C
D.body B
Solution
No horizontal external force is acting
∴ acm = 0
since Vcm = 0
∴ ᐃxcm = 0
∴ acm = 0
since Vcm = 0
∴ ᐃxcm = 0
