Answer:

-60.82 m/s²

Explanation:

recall that the acceleration due to gravity, g = 9.81 m/s²

We must also realize that during the car crash, the moving car is being brought to a stop. Hence,  it is actually a deceleration (i.e a negative acceleration)  

Therefore we must add a negative sign to our acceleration to describe the deceleration.

acceleration = - 6.2g

= -6.2 x 9.81 m/s²

= -60.8 m/s²
