Final answer:
In ice sliding, the boys' motion can be described using the principles of linear momentum, where the total momentum before and after the collision remains constant. The direction and speed of the boys' motion will depend on their initial velocities and the angle of their collision.
Step-by-step explanation:
In the context of ice sliding, the motion of the boys can be described using the principles of linear momentum. When two bodies collide, the total momentum before the collision is equal to the total momentum after the collision, assuming no external forces act on the system. This means that if one boy is stationary and another boy slides towards him, the stationary boy will gain momentum equal to the momentum of the sliding boy after the collision.
For example, if the sliding boy has a momentum of 10 kg·m/s before the collision, the stationary boy will also have a momentum of 10 kg·m/s after the collision. The direction of the boys' motion will depend on their initial velocities and the angle of their collision.
It's important to note that this explanation assumes an ideal scenario with no external forces, friction, or other factors that could affect the motion of the boys.
