A shell of mass m is moving horizontally with velocity v0 and collides with a wedge of mass M just above point A, as shown in the figure. As a consequence, wedge starts to move towards left and the shell returns with a velocity in x–y plane. The principle of conservation of momentum can be applied for :
- system (m + M) along any direction
- system (m + M) along vertical
- system (m + M) horizontally
- none of the above
Answer
(C) system (m + M) horizontally
