Answer:
<em>The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.</em>
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.
