A2.0 kg purse is dropped from the top of the leaning tower of pisa and falls 55m before reaching the ground with a speed of 29 m/s. what was the average force of air resistance?

For the presented problem, the average force of air resistance would be F = 4.34 Newtons. I am hoping that this answer has satisfied your query about and it will be able to help you, thank you and have a nice day.

F=-4.32N

Explanation:

2.0 kg purse is dropped from the top of the leaning tower of pisa and falls 55m before reaching the ground with a speed of 29 m/s. What was the average force of air resistance

Air Resistance:

is a kind of resistive force that the air applies to a particle or a system of particles when it moves or falls through it. The resistive force is always in opposite direction  to the motion of the body.

the average force exerted the air on the purse be F.

From the conservation law of energy, the work done by the air resistance will be equal to the difference between the potential energy and the kinetic energy.

.F*h=mgh-1/2mv2

definition of parameters

m=mass of the purse 2kg

u=initial speed of the purse=om/s

v=final velocity of the purse 29m/s

h=the height of the leaning  tower of pisa 55m

g=acceleration due to gravity

F*55=2*9.81*55-0.5*2*29^2

F*55=238.1

F=-4.32N

the opposite direction sows tat it is against the falling purse

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
