Question

Which ball collides when no. Of balls are placed on an axis?

Answer 1

Explanation:

Momentum is conserved in the collision. Momentum is conserved for any interaction between two objects occurring in an isolated system. This conservation of momentum can be observed by a total system momentum analysis or by a momentum change analysis.

Answer 2

In elastic collision

Applying conservation of momentum

m( 10) =m(v

1

)

v

1

=10

v

2

=0

then

mv

1

=mv

v=10

so velocity of c spherical ball

=10m/s
