An SUV crashes into a wall. The mass of the vehicle is 2,150 kg and the crumple zone rigidity is 342 kN. Assuming the safety cell is perfectly rigid, what will be the acceleration of the SUV during a crash as the crumple zone is collapsing?
–0.159 m/s2
–6.29 m/s2
–159 m/s2
–735.3 m/s2
To calculate the acceleration of the SUV during the crash, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass.
First, we need to calculate the force of the impact. The force can be calculated using the formula:
Force = rigidity * deformation
Force = 342 kN * x
Where x is the distance the crumple zone collapses.
Next, we need to calculate the acceleration using the formula:
Acceleration = Force / mass
Now let's substitute the values into the formulas:
Force = 342 kN * x
Given that we don't have the exact distance the crumple zone collapses (x), we cannot calculate the exact acceleration. Therefore, the provided options cannot be determined without knowing the distance the crumple zone collapses.
