Impulse is
The average force is
Explanation:
When a mass
undergoes a change in velocity 
, its impulse 
is
and if a force
is acting for time 
, then the impulse 
is given by
Now the mass of the spores in kg is
we calculate the impulse from the first formula:
Now that we have impulse, we calculate the average force on the spore from the second formula:
