A shell of mass 'm' moving with velocity v suddenly break into two pieces the part having mass m/3 remains stationary. The velocity of other part will be?
(2/3) v
(7/5) v
(3/2)v
none of these
As we learnt in
Kinetic energy -
- wherein
kinetic Energy is frame dependent
Mass of two piece are
Option 1)
(2/3) v
Option is incorrect
Option 2)
(7/5) v
Option is incorrect
Option 3)
(3/2)v
Option is correct
Option 4)
none of these
Option is incorrect
