Answer:
(a) They must have same direction
(b) It is not necessary for them to have same magnitudes
Explanation:
(a)
Momentum is a vector quantity. It is the product of mass (scalar) and velocity (vector). Thus, if the direction of velocity is changed, then as a result the direction of momentum will also change or its magnitude or component in the same direction will change. Hence, for the two objects to have same momentum, the directions of their velocities must also be the same.
(b)
Since, the momentum is product of velocity and mass. It is possible that two bodies of different masses with different velocities might have same momentum, provided the direction of their velocities is same.
For example, take a body of mass 4 kg moving with speed 5 m/s. It will have a momentum of 20 N.s. Now, consider another body of mass 2 kg, moving with speed 10 m/s. It will also have a momentum of 20 N.s.
Thus, it is not necessary for two objects to have same magnitude of velocity to have same momentum.
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.

Newton's Second Law<span>. </span>Newton's first law of motion<span> predicts the behavior of objects for which all existing forces are balanced. The </span>first law<span> - sometimes referred to as the </span>law<span> of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Hope this helped! :)</span>
