A 4-kilogram ball moving at 8 m/sec to the right collides with a 1-kilogram ball at rest. After the collision, the 4-kilogram ball moves at 4.8 m/sec to the right. What is the velocity of the 1-kilogram ball?​

Explanation:

momentum is a constant

[tex]4 \times 8 + 1 \times 0 = 4 \times 4.8 + 1 \times x[/tex]

[tex]12.8 = 1 \times x[/tex]

[tex]x = 12.8m {s}^{ - 1} [/tex]

if u didnt quite get that...comment me
