so... t=? a=? Vo= 30 mph V=0 ΔS=1m V^2=Vo^2+2aΔS 0=(30mph)^2+2a(1m) which resulted in a= -450mph I know g= 9.8m/s ... so I'm assuming I have to change the -450mph to m/s by diving -450/3600s = 0.125m/s I really don't know what to do next or if I'm in the right track...

Homework Statement Determine the average number of g's experienced by someone abruptly coming to rest from an initial velocity of 30mph (such as in a car crash). Take the distance involved in coming to rest to be 1 m. Homework Equations V=Vo+at ΔS=volt+1/2at^2 V^2=Vo^2+2aΔS The...
