Answer:

100kgm/s

Step by step solution:

mass(m) = 5kg

Initial velocity (u) = 0

i.e u = 0 for free fall

Final velocity (v) = 20m/s

Momentum = m(v - u)

= 5(20 - 0)

= 5(20) = 100kgm/s.

Answer:

[tex]\boxed {\boxed {\sf 100 \ kg*m/s}}[/tex]

Explanation:

Momentum can be found using the following formula.

[tex]p=mv[/tex]

where p is the momentum, m is the mass, and v is the velocity.

1. Define Variables

The mass is 5 kilograms and the velocity is 20 meters per second.

[tex]m= 5 \ kg \\v= 20 \ m/s[/tex]

2. Calculate Momentum

Substitute the values into the formula.

[tex]p= 5 \ kg * 20 \ m/s[/tex]

Multiply.

[tex]p= 100 \ kg*m/s[/tex]

The momentum of the ball is 100 kilograms meters per second.
