racing driver, David Purley, survived a deceleration from 173km/h to 0km/h in a distance of 66cm in a crash. body mass = 55kg

2. Relevant equations

V^2=u^2+2*a*d is what i have to work with at the moment, i was thinking of using a=Fnet/mass. but im having trouble finding the Fnet.

3. The attempt at a solution

honestly, i dont know where to start.
