Question

During a crash test, a car of mass m=1050 kg is crashed against a wall at a speed of 122 km/h.

Answer 1

To estimate the average force exerted by the wall on the car, you need to collect the negative acceleration of the car before it hits the wall and the velocity of the car just before impact.

Step-by-step explanation:

In order to estimate the average force exerted by the wall on the car, you would need to collect the following information:

1. The (negative) acceleration of the car before it hits the wall
2. The velocity of the car just before impact

By knowing these two pieces of information, you can calculate the average force exerted by the wall using the equation F = m(a + g), where F is the force, m is the mass of the car, a is the acceleration, and g is the acceleration due to gravity.
