Acar moving at 10 m/s crashes into a tree and stops in 0.26 s. calculate the force the seat belt exerts on a passenger in the car to bring him to a halt. the mass of the passenger is 70 kg

We have that for the Question,it can be said that the force the seat belt exerts on a passenger in the car to bring him to a halt is

F_net=2.7*10^3

From the question we are told

A car moving at 10 m/s crashes into a tree and stops in 0.26 s. calculate the force the seat belt exerts on a passenger in the car to bring him to a halt. the mass of the passenger is 70 kg

Generally the equation for the net Force  is mathematically given as

Therefore

the force the seat belt exerts on a passenger in the car to bring him to a halt is

F_net=2.7*10^3

Explanation:

first of all, we need to calculate the acceleration experienced by the car and the passenger. This acceleration is given by

where

v=0 is the final velocity of the car, after the impact

u=10 m/s is the initial velocity

t=0.26 s is the duration of the collision

Substituting numbers into the formula,

The force exerted on the passenger is given by the product between the mass of the passenger (70 kg) and the acceleration:

where the negative sign means that the direction of the force is opposite to the motion of the passenger+car.

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
