Each croquet ball in a set has a mass of 0.50 kg. the green ball travels at 10.5 m/s and strikes a stationary red ball. if the green ball stops moving, what is the final speed of the red ball after the collision?

Explanation:

It is given that,

Mass of both green and red ball, m₁ = m₂ = 0.5 kg

Initial speed of green ball, u₁ = 10.5 m/s

Initial speed of red ball, u₂ = 0 ( rest )

Final speed of green ball, v₁ = 0 (it stops)

We need to find the final speed of the red ball after the collision. Lt it is equal to v₂. Using the conservation of momentum as :

Since, m₁ = m₂

So, the final speed of red ball after the collision is 10.5 m/s. Hence, this is the required solution.                                      

this is poiselle's equation from fluid mechanic in physics. mech eng

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
