a Billiard ball with momentum of 20 kg * m/s strikes a second ball at rest and comes to a complete stop what is the change in momentum of the second ball

Explanation:

Momentum of the system is a constant when there aren't external forces..

So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s

Since a Billiard ball with momentum of 20 kgm/s strikes a second ball at rest, the change in momentum of the second ball is 20 kgm/s.

Given the following data:

  • Momentum of Billiard ball = 20 kgm/s
  • Initial velocity of second ball = 0 m/s (since the ball is at rest).

To find the change in momentum of the second ball:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity.

Mathematically, momentum is giving by the formula;

[tex]Momentum = mass \times velocity[/tex]

Since the second ball starts at rest, its initial momentum is zero (0).

[tex]Change\;in\;momentum = final \;momentum - initial\;momentum\\\\Change\;in\;momentum = 20 - 0[/tex]

Change in momentum = 20 kgm/s
