Answer:
a) J=
b) F = 
c) The force is 2551.02 times bigger than the weight of the pollen grain.
Explanation:
a) we know that the impulse J is equal to:
J =
where M is the mass,
is the final velocity and
the initial velocity. So, replacing values, we get:
J =
J =
J=
b) We know that the force is equal to:
F = J/t
where J is the impulse and t the time. So, replacing values, we get:
F = 
F = 
c) The weight W of the pollen grain is calculated as:
W = 
W = 
So, if we compare the force and the weight of the pollen grain, we get:

it means that the force is 2551.02 times bigger than the weight of the pollen grain.
