acceleration car crash g's experienced??
Acceleration is sometimes expressed in multiples of g where g=9.8m/s^2 is the acceleration due to the Earth's gravity. In a car crash the cars velocity may go from 26m/s to 0m/s in 15s. how many g"s are experienced on average by the driver??
a, 23- i know this is wrong
b, 18g
c,22g
d,23g
we have a, vi, vf and t
so something like v=v0+at
v=26m/s+ 9.8m/s^2*15s=173??
