Answer:Particulates are small, distinct solids suspended in a liquid or gas and example are dust,soot,and salt particles
Explanation:
The middle one on the list is the correct one.
The first one ... distance divided by time ... is Speed, not force.
The third one ... mass times velocity ... is Momentum, not force.
Here we can use momentum conservation as in this type of collision there is no external force on it
now here we can say
now here we can say
now by coefficient of restitution
for elastic collision we know that e = 1
now by solving the two equation
also we know that
so final speed of the nail is 6.875 m/s
