From the calculations, the mass of the pole is 82 Kg.
<h3>What is potential energy?</h3>
The term potential energy has to do with the energy that is possessed by a body by virtue of its position.
Given that;
height = 6.15 m
PE = 4942 J
mass = ??
g = 9.8 m/s^2
Now
PE = mgh
m = PE/gh
m = 4942 J/9.8 m/s^2 * 6.15 m
m = 82 Kg

Yes, you are pulling on the Earth, with equal force.
Your weight on Earth is equal to the Earth's weight on you.
I can't think of a way for you to go out and see it or measure it,
but there are two things we learn in Physics that tell us that it
must be true.
#1). Newton's 3rd Law of motion:
For every action, there is an equal, opposite reaction.
If the Earth pulls on me, then I must pull on the Earth with an
equal, opposite force.
#2). Newton's law of universal gravitation:
Gravitational force = (a Constant) · (mass₁) · (mass₂) / (distance)² .
Take a good, long, hard look at this formula for the gravitational force.
It tells the strength of the gravitational force between the Earth and you.
But it doesn't say WHICH object is (mass₁) and which object is (mass₂) !
It doesn't matter ! BOTH objects feel the same gravitational force !
answer
6000 N
explanation
every force has an equal and opposite reaction force, so the force exerted by the truck on the car is the same as the force exerted by the car on truck
the force is 6000 N
Electricity is the controlled flow of electrons. They are made to travel in the same direction at the same time. If you have an insulator, it stops or severely inhibits the flow of electrons. Such a device is found on telephone poles. Those are made of glass like materials.
you would multiply 30 by 15. because its the weight times the distance.
