Avg force on car during crash test?

In summary, the "Avg force on car during crash test" is a measurement of the average force experienced by a car during a simulated crash test. It is calculated by dividing the total force applied by the duration of the impact and is used in car safety ratings to evaluate the crashworthiness and effectiveness of safety features. Factors that can affect this measurement include impact speed and angle, car weight and design, and safety features. Measuring the "Avg force on car during crash test" is important for improving car safety and designing more durable and protective vehicles.

In a crash test a car with mass 746.9 kg collides with a wall and recoils backwards. The velocity of the car before the collision is 36.8 m/s and the velocity after the collision is -20.8 m/s. What is the average force (in N) on the car if the collision lasted for 0.85 sec?

Yes correct!

F * t = change in momentum = m(v1 + v2)

F * 0.85 = 746.9 * 57.6

So F = 50613N
 

Related to Avg force on car during crash test?

What is "Avg force on car during crash test?"

The "Avg force on car during crash test" is a measurement of the average force that a car experiences during a simulated crash test. This measurement is used to evaluate the safety and structural integrity of a car.

How is the "Avg force on car during crash test" calculated?

The "Avg force on car during crash test" is calculated by dividing the total force applied to the car during the crash test by the duration of the impact. This gives an average force value in units of Newtons (N).

What factors can affect the "Avg force on car during crash test?"

There are several factors that can affect the "Avg force on car during crash test," including the speed and angle of impact, the weight and design of the car, and the effectiveness of safety features such as airbags and seat belts.

How is the "Avg force on car during crash test" used in car safety ratings?

The "Avg force on car during crash test" is one of the key metrics used in car safety ratings, such as those from the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). A lower average force value indicates better crashworthiness and a higher safety rating.

Why is it important to measure the "Avg force on car during crash test?"

Measuring the "Avg force on car during crash test" is important because it allows us to evaluate the safety of a car and make improvements to its design. By understanding how a car responds to a crash, we can make changes to increase its structural integrity and protect the occupants inside.
