During a crash, a race car driver decelerates from 48.0 m/s to 0 m/s in a distance of 14.9 m. If the drivers mass is 70.0 kg, what is the average force acting on the driver during the crash?
This is what I have so far. Am I starting right?
vf2-vi2 /2deltaX
(0-48)2( (103 m/km)2 (1 h/3600 s)2/2(14.9m)
-4.8x103m/s2
is what I had so far. It didn't save when I posted.
