A block of mass 'm' moving along a straight line with constant velocity 3 V collides with another block of same mass at rest. They stick together and move with common velocity. The common velocity is
Options
- A3 v 2
- B2 V
- C3 V
- DV
Correct answer
A. 3 v 2
Step-by-step solution
A block of mass 'm' moving along a straight line with constant velocity 3 v collides with another block of same mass at rest. They stick together and move with common velocity. The common velocity is 3 v 2 . (m+m) v₂=m 3 vv₂= 3 2 v
