Calculate the momentum of a 5 kg ball in free fall at 20 m/s. Show your work.

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.

Explanation:

Momentum can be found using the following formula.

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.

2. Calculate Momentum

Substitute the values into the formula.

Multiply.

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

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
