Thank you all!

So I'd just change the end to -1 764.71m/s^2 = a And mass = 70kg Then I multiple those two together to get the impact force/final answer?

v1 = 48m/s a = (v2 - v1)/t.] = 0 - 48m/s = -48m/s / 0.0272s a = -1 764.71m/s that doesn't seem right

Whoops, I'll be sure to do that, thanks. So then do I use the acceleration fomula or the force fomula?

So v2 = 0? v1= 48m/s^2 t = 0.0272s

So you'd have to mutiple the number by 1000 then divide by 3600? 172.8*1000= 172800 172800/3600= 48m/s/s

Am I meant to use the acceleration formula for that? a= v1 - v2 / t

Homework Statement During a Formula 1 race a car that was traveling at a speed of 172.8 km/h crashed into a wall. When the car hit the wall it came to a complete stop in 0.0272 s. If the driver of the car holds a mass of 70kg, calculate the impact force he experienced. Homework Equations I...
