A car is traveling at 25 m/s when it runs off the road and hits a utility pole. The car stops instantly, but the driver continues to move forward at 25 m/s. The airbag starts from rest with a constant acceleration from a distance of 50 cm away from the driver and makes contact with him in 9 ms. What is the acceleration of the airbag?
My answer was a = 1234.568 m/s, but its wrong.
These were what I believe to have been the known quantities:
vi = 0
a = ?
t = 0.009 s
d = 0.050 m
I used this equation to solve the problem:
d = vit + 1/2*a*t2
What am I doing wrong and what is the right answer?
Thanks
