Answer:
1.5 m/s
Explanation:
Conservation of momentum means the momentum of the system before the collision is the same as after.
The before, after momentum of each ball is ...
5 kg ball: (5 kg)(2 m/s), (5 kg)(-1 m/s)
10 kg ball: (10 kg)(0 m/s), (10 kg)(v)
The sum of the "before" products is the same as the sum of the "after" products:
(5 kg)(2 m/s) +0 = (5 kg)(-1 m/s) +(10 kg)v
(10 +5) kg·m/s = (10 kg)·v . . . . . add (5 kg)(1 m/s) to both sides
v = (15 kg·m/s)/(10 kg) = 1.5 m/s
The speed of the larger ball will be 1.5 m/s. Its direction of motion will be the opposite of that of the 5 kg ball after the collision.
Answer:
Each part of a two-dimensional vector is known as a component. The components of a vector depict the influence of that vector in a given direction. The components of a vector depict the influence of that vector in a given direction.

Answer:
Predictive
Explanation:
There is a wide variety of life cycles applicable to project management. In this regard, we currently have as a reference two somewhat extreme approaches that mark two very different ways of dealing with projects. The predictive approach and the agile approach.
A predictive approach involves a great effort in initial planning and re-planning every time changes are accepted in the project. Therefore, this approach is recommended for changing but not highly changing environments. Although this approach is applicable to any type of project, clear examples of application would be the construction of a subway line, a bridge, the development of critical software. That is, projects where correct and detailed planting is key.
