Answer:
Final speed of striped ball is 3 m/s in left direction .
Explanation:
Given :
Two billiard ball with the same mass moves toward the left at the same speed 3 m/s .
Let , us assume right hand side direction to be positive and left hand side direction to be negative .
Also , let speed of ball after collision is (striped ball ) u and (solid ball) v .
It is also given that the collision is elastic .
Therefore , kinetic energy is conserved .
...... ( 1 )
Also , by conserving linear momentum .
We get :
...... ( 2 )
Putting value of u from equation 2 to equation 1 .
We get :
And , u = -3 m/s .
Therefore , final speed of striped ball is 3 m/s in left direction .
Hence , this is the required solution .
Two Sets of solid double yellow lines with spaced two or more feet apart indicates that Do not drive on or over the barrier.
<h3>What are the line colors in lane control?</h3>
Solid yellow lines - it is marked at the center of a road and used for two-way traffic.
Broken yellow lines - It indicate that you may pass if the broken line is next to your driving lane.
Two solid yellow lines - It indicates no passing or Do not drive on or over the barrier.
Two sets of solid double yellow lines are considered a barrier , make a left turn, or a U-turn to cross it.
