The answer should be d because they are constantly rotating
The answer would be 54 m/s as the maximum speed
C is the answer because it mix and water combining together
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 .
Answer:
Momentum of system = 37.2 Kgm/s.
Explanation:
<u>Given the following data;</u>
- Mass A = 5 kg
- Velocity A = 6 m/s
- Mass B = 12 kg
- Velocity B = 0.6 m/s
To find the momentum of the system;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
<u>For object A;</u>
Momentum A = 5 * 6
Momentum A = 30 Kgm/s
<u>For object B;</u>
Momentum B = 12 * 0.6
Momentum B = 7.2 Kgm/s
Next, we would determine the momentum of this system using the formula;
Momentum of system = Momentum A + Momentum B
Substituting the values into the formula, we have;
Momentum of system = 30 + 7.2
<em>Momentum of system = 37.2 Kgm/s.</em>
